Do you have ADHD? I read once that for normal people caffiene pushes dopamine levels too high, and stops them from sleeping, but for people with ADHD caffeine can push dopamine levels from too low to normal, calming them and helping with sleep.

I dont really have ADHD, but one time on nat geo channel i saw this video where they test two people , they were supposed to not sleep. after 12 hours they both were given coffee, one was allowed to sleep 30 mins, other was not . the one who had a nap recovered really well but the others conditioned worsened and he went to sleep even tho he didnt wanted to, his body gave up.

I do, nicotine works this way for me.

> if you drink coffee and then sleep immediately

Alas, being of a certain age means that any kind of liquid before bed will result in an early-hours wakeup to relieve the bladder - negating any potential sleep benefits :(

That’s called a power nap. But you have to be a good sleeper in the first place. If you are not able to fall asleep before the caffeine kicks in, you’ll have a pretty different night/nap.

I have heard of people who say creatine helps them sleep. Creatine is technically not a stimulant, but in most people it causes a state of mental activation that would make it hard to sleep. I suspect you and the people who sleep better on creatine may have something in common.

This is funny. I started mixing ~3g of creatine into my morning coffee a couple of weeks ago. I never thought of it being stimulating or activating, but it's certainly possible: I usually don't stick long enough to things like this to form a habit, but my brain seems to nudge me into keeping up with it...

I don't find it dissolves or stays in suspension - at the end of the coffee most of the creatine is at the bottom of the mug. Which is a pity as otherwise it would be very efficient, tip it in while the machine makes the cup. Are you stirring it lots or similar?

The creatine I use is finely powdered and it immediately dissolves in very little boiling water. I add it to the second coffee of the day: first one is from the espresso machine for pleasure while waking up, second one is using instant coffee to maintain stable blood caffeine levels. The crema-faking bubbles from the instant espresso powder probably help getting the stuff to dissolve. Then drink it hot and quickly :)

Surely must be another method that doesn't ruin a perfectly good cup of coffee

That's why I use it with instant coffee ;) not much to ruin when your expectations are already low! Also, you need boiling water to properly dissolve the stuff. But to be honest: the coffee feels thicker, but there's no distinct change in taste due to creatine.

How much caffeine you consume on average? Some might get withdrawal symptoms asleep if the intake is very high.
