Don't do coricidin if you decide to do dxm.It has CPm in it along with dextromethorphan.Just go to like a rite aid or somethin,and get a no name brand of cough syrup,make sure that the only thing in it dextromethorphan,itll say like 15 mg/5 ml teaspoon.AS far as if it's that good,iv'e had a lot of bad experiences with it,but alot of good ones.HAven't done it in aong while tho
Peace
