Nurofen is painkiller tablets that can be bought over the counter. Bottom middle is Ritalin I think which is an ADHD med and the other is diazepam which is used for anxiety. Both Ritalin and diazepam are prescription only.
The only one of those I do is headache medicine, and only for intense headaches, and I only take half the recommended dose for some reason.
Well, I also have caffeinated sodas sometimes, but it's for the flavor, not the caffeine. Pretty much mid-day only; the caffeine doesn't make a difference.
