I want to improve my reading and comprehension concentration for a few hours at a time using drugs/chemicals/foods only. Yes I believe you that meditation and exercise are the ideal solutions but I just want to be my usual averagely healthy self when Im not concentrating. I also don't care about negative short-term after-effects. [more inside]

Has anyone tasted a coffee cherry? How about a guarana berry? Most of the caffeine we ingest is derived from these apparently-edible little red fruits, but I have never seen a fresh one in the U.S. Is it possible to mail order some? What do they taste like?
