Caapi sounds like it is worth the extra expense. Thank you all for the replies, but I have one more question to ask. If I wanted to brew some of the tea, could I add vitamins, choline products, piracetam and other use full things into the tea with out any problems? I loathe taking pills, and I could much more easily drink a bad tasting tea every day, rather than swallowing a bunch of pills.

Thanks.
