Any reason why drinking coffee makes me sleepy?
It's like I'm immune or something.

I've googled it, but have found no reasons, just similarly-effected people also stating caffiene makes them sleepy too.

What did you expect was going to happen?

Small amounts of stimulants can cause drowsiness in people with ADHD

Probably just some genetic anomaly. Nobody responds to drugs in the exact same way. That's why the pharmaceutical industry is retarded.

No, this is why you're retarded.
Welp, the drug only works for 99.9% of the population. Guess that makes it useless. Throw it in the garbage.

You've developed a resistance.

Happens with all stimulants.

Try drinking 1 cup of coffee and 1 cup of water OP. Basically 50-50 and you should feel much more awake when taking caffeine like that.

caffeine releases dopamine and dopamine can make you sleepy. I've experienced the same effect.

>> No.5337897

you have a caffeine dependancy. stop drinking so much soda/coffee and u will get back to normal over time. its probably good for your health to do it too

Drinking a coke makes me sleepy, but expresso wires me up like crazy.

Probably because there's a lot of caffeine in espresso

Caffeine makes your body flush its dopamine reserves. Any way since there is an elevation in your bloodstream and your brain of dopamine your body goes "UH OH, better drop those levels", so it releases enzymes to break that down into norepinephrine and epinephrine, basically, those are adrenaline. So your body then gets elevated levels of adrenaline, which is responsible for that coffee rush, and then your body goes "UH OH, better drop those levels", so it releases enzymes to break down the adrenaline, because there is a lot of extra adrenaline it releases a lot of the enzymes, and they work overtime, to get rid of the extra adrenaline, and they end up taking your levels below normal, and that is responsible for the tired feeling you get.
Also if you have ADHD you should never touch caffeine, it will make your inattention much worse over time, because people with ADHD already have problems with dopamine regulation, so constantly dumping large amounts into your brain is bad.
