You can also drink white tea and green tea (leaf tea variants) which are milder- I think the white has no caffeine, but the green might have a small amount? You would need to check for definite. If it is ok, clipper teas also do a white with mint tea which is totally addictive. You can find clipper teas in most supermarkets. They also do a white with ginger, which is still a leaf tea and a white with cinammon but these are harder to find- wholefood stores usually have them. I have not had the white with cinammon, just in case, but I think it would be allowed on SS.
I am turning into a tea bore!
