I build tolerance to caffeine very quickly for some reason. One night I drank two redbulls so I could finish a project (I had been drinking a lot of coffee and energy drinks during that period) and decided to take a quick nap before going into crunch mode and ended up sleeping the entire night.

I had a redbull yesterday at 17:30 and fell asleep with no problem at 22:30.

If I want the true effects of the energy drinks I have to use them sparingly or else my tolerance ramps up and it doesn’t give me the energy buzz but kinda makes me sleepy...

Caffeine affects sleep quality as well as the ability to fall asleep. So just falling asleep doesn't mean you aren't suffering any negative effects.

Yes, I can sleep even with very high amounts but my sleep quality is horrific. Although sleeping through the night you wake up like you didn't sleep at all.
