i was planning to do the deed today as well...not pills though. i read somewhere that guaifenesin leads to naseau and vomitting...when i read this, i checked my label (robitussin dm) and it said it contained 100mg/5mL teaspoonful of guaifenesin.

is this enough to cause vomitting if im 200lbs and plan to take a 4oz. bottle? any tips or ANYTHING? thanks.
