I'm a girl and I weigh about 120, and I want to try Delsym (DXM polistirex). I don't want to trip out or anything since this is my first time but I just want something euphoric, since I'll be smoking weed too while I'm on DXM. 5ml DXM polistirex is equal to 30mg of DXM HBr, so how much should I take of the DXM polistirex? I don't want to go overboard with it for my first time. Also, does anyone have any tips about getting high on Delsym for the first time?
