Been there, Done that, trying to forget it all. For the most part, I'd agree with GP. Made some pretty impressive memories and now have some really neat stories to relate to others, but on the whole a very bad part of my life. Unlike others here, I DID have a serious problem for about 6 months. Altogther I spend 2 or 3 years on the wrong road of life. And it's really really hard to get off that road after a short while.
I see a lot of my friends who are still on that road or are starting on it and I try to warn them but unfortunatly, they don't listen. There was a small group of us who all decided we'd had enough of spending an insane amount of money (once spent $3000 in 2 days myself!!) and we all decided to quit together. If we hadn't I don't know if any of us could have. It was hard.
I had to keep busy somehow so I got myself 4 jobs. 2 were full time, one part time and the other filled in where I wasn't working. 16 hours every day except for Monday's where I only worked 8.
On the otherhand, I gained IMO some unique skills. I have now developed the ability to Detect Addtictions. After a short time, I can now tell if someone is having an addiction to something (drugs, alcholhe or other) because I know what the signs are. In some cases, I can actully tell what the drugs are because of physical manafestations. eg: cocaine addicts skin begins to look almost transparent.
Didn't mean to spew all that, but hey you asked for it
