I can't drink coffee at all, any more.
Makes me
. Big time. (gerd, diarrhea, etc, etc.....)
I recommend trying a good quality
black tea. Though you ahve to remember that the caffeine in tea is a time-relaease rather than instant like coffee. You can take a caffeine pill at least until you get a level of tea-type caffeine in your body.....
Black tea has more caffeine than green, & white tea has less than green. (Red "tea" is actually not at all; it tastes nice, but has no caffeine at all).
