i just bought two packs of robitussin cough gels. thing is, the two active ingredients are DXM and guaifenisen. ive heard it can cause vomiting at high doses... anyone have any experience with it? do you always vomit? and do you vomit the entire trip, or just once or twice at the beginning? any info would be appreciated.
