It lasts for about 6-8 hours, and you feel sort of "above baseline" for another day, at least I do.

It's good that you don't want to do triple-C's. All too often I see people who do DXM with CCC's only, and that's it. They're BAD. The product that I use is called "Dex-Alone". They're these little Gelcaps that you can buy, they have 30mg of Dextromethorphan HBr, and that's they only active ingredient. They work rather well. I'm not sure about which cough syrup is safe to use, maybe someone else will know.

You are probably going to want to take about 500 mg your first time, and then increase it with each subsequent time.

You probably won't be hungry.

You might want a cigarette, it might help to chill you out.

You don't actually "trip balls" on DXM... it's kind of hard to describe. It's fun, though. Best of luck.
