Although the rest of the post was wrong, she did get one thing right. It was the wrong kind of cough syrup. Yours is 'cough and cold', you need to go for just 'cough'. The only DXM preparations which are safe to use are the ones which contain Dextromethorphan Hbr as the ONLY active ingredient. The active ingredients are listed on the back of the box. As for Triple C, (Coricidin, aka CCC) stay as far away from it as possible, as it is pretty dangerous because of the antihistamine in it. I recommend Robitussin Cough Gels, which come twenty to a bottle, and total 300mg DXM. It sounds like maybe you DID trip, but were just too stoned to realize it. Next time, I'd suggest using DXM by itself to get a feel for it. As for puking, many many people puke after ingesting, and for some it's part of the DXM ritual.
