Anybody else get much worsened muscle fatigue after consuming tannins? This is annoying since even decafinated tea/coffee and green tea have tannins in them that leave me feeling very much weaker even than my usual weakness. Even other teas with tannin, such as Pu'erh (asian tea) have this effect. I can handle not having caffeinated tea or coffee but I can't even have a small cup of decaf orange pekoe, weakly brewed, without being drained of what little energy I might have. Jeeeeez, I just want a cup of tea! Most herbals are not satisfying and are bad for tooth enamel if I have them very often (otherwise I would drink rooibos). The only thing I can drink on a regular basis is chamomile and it isn't always satisfying. I have very few 'bad habits' lifestyle-wise, but even buddhist monks don't have to go without decaf green tea!
