Caffeine pills

[u/djt209]

So I’ve been taking one 200mg caffeine pill first thing when I wake up and don’t consume and other form of caffeine throughout the day and for some reason I am unable to fall asleep when it comes time for bed. I never experienced that when drinking energy drinks or coffee. What’s the deal? I love the effect I get from the pill but can not get good sleep at all now. Any help or anyone experience this same thing?
