I like to drink strong caffeine products in the evening especially right before going to bed when I’m already tired. The time till falling asleep makes the caffeine kick sort of different. Feels like you are really tired like you haven’t slept in days.
As I only consume caffeine you have to get all out of it
I need to be careful with caffeine because I get hand shaking, jaw and tongue movements and fast eye blinking after drinking coffee. I think it may be tardive dyskinesia but I have not confirmed that with a doctor yet.
