Keep reading to learn more.

I’ll also share with you one really safe and better Phentermine replacement I discovered when researching for this piece. It does everything Phentermine does and even more.

Before we delve into the question of whether Phentermine causes you to sleep and or feel tired – lets us remind ourselves what Phentermine is and how it works in the human body.

What is Phentermine?

Phentermine is a drug that is used for weight loss. It belongs to the class of drugs called amphetamines and it works by suppressing the appetite.

Taking phentermine helps suppress your appetite because it activates the central nervous system and causes a release of norepinephrine. This hormone is responsible for increasing heart rate, blood pressure, and breathing rate.

In other words, phentermine speeds up the body’s metabolism, which can help you lose weight.

Lets say you’re into fitness or an athlete looking to suppress your appetite and lose weight. Taking Phentermine for a short while is a great tool to have in your arsenal.

How does Phentermine work?

The hypothalamus – a small, almond-shaped structure in the brain – is responsible for controlling appetite, body temperature, water balance, and other important functions.

When you take Phentermine, it sends a signal to the hypothalamus telling it to release more norepinephrine. This hormone then tells the body to break down stored fat and use it for energy.

This means that more of the hormone is available to activate the central nervous system.

Phentermine also binds to receptors in the brain that are responsible for controlling appetite. When these receptors are activated, they send a signal to the body that tells it to eat less.

So, Phentermine not only activates the central nervous system but also blocks the receptors that control appetite. This combination of effects can help you lose weight quickly.

Now that we know a little more about what Phentermine is and how it works, lets discuss whether it causes fatigue or sleepiness as a side effect.

Why Does Phentermine Cause You to Feel Tired?

Yes, Phentermine will make you feel tired because it is a stimulant. It works by increasing your heart rate and breathing rate, which can make you feel exhausted.

It also increases the amount of norepinephrine and dopamine in the brain, which are two chemicals that help to stimulate the central nervous system. When these chemicals are increased, they can make you feel more alert and awake.

There are other several reasons why Phentermine might cause you to feel tired.

Here are the reasons:

  • Phentermine speeds up the body’s metabolism, which can cause you to feel tired

When your body is working hard to break down stored fat and use it for energy, it can make you feel tired.

This is especially true if you are not used to taking Phentermine or if you are taking a high dose.

  • Phentermine can cause you to feel anxious or nervous

Anxiety and nervousness are common side effects of Phentermine.

When you’re feeling anxious or nervous, it’s natural to want to take a nap to calm down. This is another reason why Phentermine might make you feel tired.

In some cases, the anxiety and nervousness can be so severe that they interfere with sleep.

  • Phentermine can cause you to have a lower than normal blood pressure

When your blood pressure is low, it can make you feel tired and lightheaded.

This is another common side effect of Phentermine and one that often goes away after a while as your body gets used to the medication.

Does Phentermine Cause You to Feel Sleepy?

Phentermine is an appetite suppressant, not a sleep aid. So it should not cause you to feel sleepy. In fact, from my research, I found out that it may cause difficulty in sleeping in some people.

While some people experience drowsiness, others felt more alert. I believe that it depends on the person taking it and their body’s reaction to the drug.

If you are feeling sleepy after taking Phentermine, speak with your doctor about it as this may be a sign of another health condition.

Otherwise, try to drink plenty of water, eat healthy foods, and get regular exercise to help you stay alert and awake.

Again, Phentermine can cause you to feel tired for the following reasons:

  • It speeds up your metabolism, which can make you feel tired
  • It can cause you to feel anxious or nervous
  • It can cause you to have a lower than normal blood pressure
  • It reduces energy levels

Before I delve into one of my recommended alternatives to Phentermine (discovered recently) and how they work in suppressing your appetite and losing weight – lets quickly cover some other side effects.

Other Side effects of Phentermine

Here are common effects:

  • Dizziness
  • Headache
  • Nausea
  • Constipation
  • Diarrhea
  • Bad taste in your mouth
  • Constipation

These effects are mild and last for while. But it should be monitored carefully if it worsens over time.

On the other hand, there are serious side effects as well – they include:

  • Insomnia (trouble sleeping)
  • Erectile dysfunction in men
  • Hypertension (high blood pressure)
  • Primary pulmonary hypertension (PPH)
  • Restlessness
  • Tremors
  • Severe headaches

The above effects are life-threatening and always warrant a visit to your doctor.

Are there any alternatives to taking Phentermine?

You may already know this – that Phentermine has been a Schedule IV controlled substance for a while now. And, as such, it’s not available over the counter like some of its alternatives are.

There are a few that I’ve found and will be covering shortly – but first, let me ask you this:

What if there was an alternative to taking Phentermine that had ZERO side effects, uncontrolled and available over the counter, online, and worldwide?

Would that be something you’re interested in?

Well, a few weeks ago while I was conducting research online I stumbled on a brand called PhenQ.

After a bit more research, I learned that PhenQ does exactly what Phentermine does but without ANY of the side effects.

PhenQ hunger suppressant is FDA approved. Suitable for men and women without a prescription. Doesn’t matter if you’re a vegetarian or vegan.

How PhenQ Suppresses Your Appetite and Helps You Lose Weight

Final Thoughts

So yeah, Phentermine may cause you to feel tired. But not sleepy.

However, there are alternatives that do not have any side effects. Always speak with your doctor if you are experiencing any adverse effects while taking Phentermine.

Regardless, I wouldn’t recommend you – as an athlete or fitness enthusiast – to go looking for an appetite suppressant like Phentermine because you can only get through a prescription from a doctor.

It is a controlled substance. This will make it a bit difficult to get without going through an illegal means.

This is one of the reasons why a replacement like PhenQ was manufactured in the first place. Check out their official website for more information. They ship worldwide.
