I've been taking them for a while, I just go and buy a 100 tabs. I took two once and it was a big mistake, had a huge headache and I couldn't breathe very well. Also my heart was beating really fast. One tablet makes me feel really light and happy and full of energy but I wondered if there were any long term implications of taking caffeine pills. I don't do it every day, maybe 2-3 a week. I was thinking of upping that. I recently quit drinking energy drinks and soda because my family has a history of diabetes and I eat like shit so I wanted to mitigate some of the risk there.

So what's your take, and your experiences with caffeine pills?
