I don't know if the question went through or not. does zofran and phenegran cause weight gain?

No.: Zofran is a drug which is quite effective at stopping nausea and vomiting. Usually prescribed for cancer pts on chemo. Phenergan an antihistamine also good for reducing vomiting but not as effective. Delta-9 THC is quite effective as an antinauseant but is not in the standard pharmacopea, but you live in Colorado so if you need it go for it! The last gives U the munchies though!
