This being a HR site, I would say start low.. no harm. Take one see how u feel. People vary in their sensitivity to opiates.. See how u feel in like a half hour.. if u need more, add another. and another. I would say if your a big guy, 4 should put u in a good place. if ur opiate naieve, maybe even 2 or 3. but start low. can always do more drugs. cant do less once u did them. =)
