Caffeine pills sick?

I took a caffeine pill the other day for work, I know they give you loose stoole, but I got diherea and had an upset stomach for a little over a day. Anyone else experience this or have any comment? Thanks

There have been periods of time that I've taken caffeine pills regularly and never had any problems. If you get sick taking them, maybe you should try something else.

I got really nauseated when I took a Vivarin on an emtpy stomach..it was torture, you have to eat something or drink milk before to coat the stomach. Those things are pretty strong. Sounds like your symptoms were definitely worse case.
