Nioxin hair products symptoms and conditions

I am participating in a research study for Wellbutrin helping smokers to quit. I am 25 years old. The study is a double blind study so there is a possibility that I am on placebo...but judging from my feelings - I am not. I have been on wellbutrin for 8 days now. I went from 150mg to 300mg in the course of 3 days. My symptoms/side effects include feeling "blah", not having interest in conversation, coordination problems (I have had issues with walking up and down stairs; almost to the point of falling), small episodes of memory loss, and I am thinking possible hair loss. The hair loss is the most devastating to me and I am going to stop taking wellbutrin because of it. I will find another way to quit smoking - there is no sense in taking something that is going to make me feel horrible about myself. Has anyone quit taking it and have their hair grow back?
