Thanks for the reply. I have never tried yerba mate. I will look it up on the Net and investigate.
The only problem that I have sometimes with coffee is after I drink it I will begin to drip sweat under my armpits. So I will move bowels and then begin sweating. I don't have a fast heartbeat or feel uncomfortable but will just begin to sweat. And then it stops once I get some food in me. Freaky!:D
Now if I drink coffee after dinner, I am fine. No sweating and no problems sleeping either. Drinking coffee after dinner is a rare occasion so not a normal ritual.
