How is that any different than coffee? My wife is a nightmare when she has not got her caffine fix. I don't see that as being dangerous though, except that coffee is a natural laxative. People feel better when consuming food as well and most people get upset when they have not eaten in a minute. I think if we could get a study of dependency and any negative effects that comes with it, I would be super excited to read about it.
Shoot me a link on your articles about the subject, I am curious. Not convinced of course lol, but surley curious.
