Coffee and Caffeine FAQ

I'm 145 pounds and i started taking some weight loss pills. It said not to take more than 3 a day.
I knew they contained caffeine but i didn't know how much. (200mg) per pill. I've been taking 3 a day, one after every meal. Today I took the first one and then i had a javalanche. My heart was pounding, but i took the next pill after lunch.
My heart has literally been sore all day, even now at 1am it hurts and my heartrate is at 85bpm when it should be 60. Some people probably don't know that weight loss pills will do this to you, so heads up. I didn't even take the third pill today. From now on, I think one weight loss pill a day, plus lots of water is the way to go.
