Why am i always sooo tired?

Have you ever had a sleep study? You may have sleep apnea where you stop breathing a bunch of times in the night, making the sleep not restful. It's an easy test- you just wear a device overnight that captures position, breathing, heartrate and oxygen saturation. It gets analyzed by a respirologist and if positive you can get a CPAP machine or some other possible remedies.

Some times for me it's lake of sleep or I slept to much! Or I drinked a lot of energy drinks and I exerted more energy than Ian took that led me to yawn one time and I was tired the rest of my shift at work

I had the same, tired all the time, even though I slept well. After visiting the Dr and blood tests the cause was I had a under active thyroid. This can be a cause of tiredness.

If you look into it there’s other things that have higher caffeine

Poor quality sleep, poor quality diet, iron deficiency, chronic fatigue syndrome, too much fapping, one of those 👌

Do you drink water, keep hydrated?

That happens to me too

It can be very difficult when you've already built up the habit. But try not taking any coffee for a while. You know the result will be the same for your workday. But in this way, there's hope that your sleep will be much easier.

Have you checked with a doctor?

Too much masturbation.

Depression?
I had that with Dysthymic Depression.
