hey, i just wanted to point out a couple bad side effects from dxm. Firstly that whole Oney's lesions idea is definitely possible. It hasn't been proven but it is possible. In my own experience i have noticed definite problems "thinking" for a couple days after using. The first couple dayswere reallybad. In general this problem can lasts weeks or who knows how long. I had a definite inability to solve complicated problems and remember complicated things such as biochemical reactions for a biochemistry class. This certainly isn't good if you are trying to get good grades. I also noticed just an inability to think about things, i didn't know what i wanted to think about, but i couldn't come up with anything to think about either. Usually my brain is constantly thinking about something, ideas, analyzing things etc, but dxm blocked my ability to do this which was not good at all. Eventually the brain seems to get back to normal, but abnormal brain function is definitely a scary thing.
