IMO: The best potentiator = carisoprodol. Its the only one I use. 60mg hydro with 700 mg (2 pills) of carisoprodol (soma), aka Vegas Cocktail, is the best. Diphen and benzos dull the high and DXM and gfj never seemed to work for me.
I used to laugh so hard back in high school when people said smoking a cigarette after getting stoned increased your high 33.3%
Yes, they said "33.3%"
