Alright i remember reading something in cough syrup will get you sick/ is bad for you. Will Guaifenesin do any harm/ have any bad side effects?
i would avoid it... heard it just makes you throw up choke... just get the tussin with out it... be better off
yes, it is. http://erowid.org/chemicals/dxm/dxm.shtml read up on that before doing dxm. might help you out. also when looking for the right product make sure the ONLY active ingrediant is dextromethorphan, if it has any others something bad is probably gonna happen.
