ok, i have 2, four ounce bottles of robotussin with just dxm, im 6'3" and 265 lbs, how many mg's do i need for a nice trippy feeling, i still need to be able to control myself though, my parents are visiting for the weekend
I don't know how many mg's of DXM are in each of your bottles, but for a first-time user at your height/weight, I'd say about 350mg should do you good, without making a fool out of yourself. Beware though, that motor functions will be impaired, walking becomes ....hard. Peace, have fun.
I've come up in an hour before, but depending on dosage and stomach contents, it can take up to two hours.
You're a heavy set guy (no offense). I took 300MG and saw little effects, fun but not much. I'd recommend a dose of 500 - 600 MG, 600 would be pretty fun.
