Dude my fucking tolerance wont go down either. I waited 4 MONTHS! (like thats even long at all.. xD) And I still had to take quite a bit.. I took 1200mg. At first I took 400mg, I thought itd be enough.. NOPE! Such a waste of 20 dollars the magic wasnt even there.
Anyways yeah its better to listen to unnk I wouldnt advise it at all, but can't really say anything because shit happens. If you do it just don't do anything stupid.
We used to have these glasses with a shot thing in the middle and a cup around the shotglass I forget what theyre called.. They are for like bomb drinks. anyways, we'd fill the cup part with 2oz of delsym and some sprite/orange soda depensing on the flavor, and the shot glass part with vodka.. Oh god good times.. Two or three of those over the course of three hours and you couldnt walk if you tried xD
