I can't tolerate caffeine well. I never drink coffee, and I had to give up black and green tea last year. They upset my stomach for days. When I was younger, coffee would give me terrible jitters, and then the stomach intolerance started.

I just drink water now, and sometimes some ginger ale diet--Vernor's-- maybe one a day in hot weather. Even peppermint tea started to bother me. That menthol attack I had with the new cool blast mints, did me in. So no more mint tea either. I might try some lightly when it gets colder...but I am not eager to do so.
