Yeah, I've had problems with DXM in the past. It started in 9th grade when I'd buy tussin every time I got five bucks.. In tenth grade my grades suffered because I couldn't concentrate on anything because I couldn't get my mind off DXM. Around that time, I came home tripping on third-plateau, (The walk home through the rain was quite an adventure.) my mom found out what I'd been doing, told me how I could've died, blah blah started crying etc. I tried convincing her that I knew what I was doing to no avail. Soon, she'd find everything from sacks of weed, to empty tussin bottles, to a bunch of empty whipped cream cans all the time. I lost her trust. One day, I found out that she had cancer, and that was most of my motivation to quit. I felt (and feel) extremely guilty for any drug use. I still use DXM, but at reasonable intervals to keep a sense of responsibility.
All that aside, I have to say that I have much respect for you. You seem to know exactly what you're talking about, no matter what drug is being discussed. And good luck to Juggalo, I know quitting's a bitch and a half.
