It seems awfully complicated to get a tendency to hallucinate (hallucinations can be caused by lots of different medicines/herbs/brain problems) if you have to either drink 7+ cups a day versus less than 1. I don't know any coffee/tea/soda drinker who drinks less than a cup? So, what happens to the tendency if you drink 2-3 cups? And what the heck is a "tendency" to hallucinate
