I have been on it for 9 days for Bronchitis. I only have a couple more to go. From what I read here, it's a good thing. cause for the past 3 days, it's just been this large wave of depression. None of the other stuff, unless I take it without eating, then I feel really sick. But I was just floored, cause I proposed to my girlfriend the day before my depression hit. This stuff is dangerous, and shouldn't be taken if there's another way.
