It lasts from 5 to 8 hours on one dose, you can increase the time it lasts by taking more later on.

Robitussin Maximum Strength Cough syrup is what I use, one 4-oz bottle has 354 mg of DXM in it and for a first timer is plenty.

You won't be hungry or if you do get hungry, you won't be able to eat, at least I can't.

Cigarettes are nice when your on it, if you blow the smoke out of your mouth slowly, it's cool to look at, but personally, I don't smoke as many cigs when on DXM cause I don't want them, but I do (doesn't make sense, I know)

It's more of a dissocitive drug, meaning you don't really "trip", but you'll feel seperate of your body.
