never taken a caffeine pill or anything. I don't drink coffee. and I rarely drink sodas. The only caffeine I get is from the occassional Iced Tea, or the rare soda.
I shook the addiction long ago. When I stopped drinking so much tea and soda....I had a mean headache for a few days because I just stopped cold turkey. I decided to taper it off so my head wouldn't feel like it was gonna explode.
