I love tea, stopped tolerating coffee 20 years ago, but often can get away with a little black or green tea but it can really wire me and drop my energy like hypoglycemia. This summer as I started using dramamine and benadryl regularly for sleep I felt the need for morning iced tea to wake up and was going pretty well but lately I think it is increasing oxygen hunger, almost like doing coke or something, its awesome for 2 hours and then it sucks for 5 hours, just need to lie around and weird things going on with pressure systems in the body then. I think the heat makes it worse even when yr in a/c. i want to continue with an iced tea ritual but does anyone know a tasty tea herb that is good for us too and might help energy without the downside of caffeine? not gingko or gotu kola for me either btw, feel weird on 'em.
