First of all, I'd like to say, out of all the DXM methods I've used, taking a lot of those robo cough gels makes the side-effect of not being able to piss the worst, the other night I took 48 of them, 720 mg total and the fact that I couldn't pee pissed me off, all in all, it was a good trip, watched a lot of Family Guy and Aqua Teen, but I had to piss really bad and couldn't do it for the life of me which brought my trip down a little. I reccomend taking taking about 40 of them the next time if you plan on going that route, but the best route I've found doing DXM is extracting it out of Triple C's and just doing the pure DXM powder, you can actually piss for the most part this way and this is what I normally do unless I'm feeling too lazy to do it, then I use the cough gels. But if you wanna know the extraction process, check out http://dextroverse.org/txt/cccextraction.txt, I'd explain it, but it takes too long. Good luck and let me know how it goes, one last thing, if you plan on doing this extraction, use about a box and a half or 24 pills, which is perfect for a 3rd plateau trip (more then enough actually, but as you do lose some of the powder during the process, it will make up for it by using more then nessicery) later man.
