As someone who HAS self medicated (with ecstasy being the exception, only because it wasn't around at the time), with these and several other street drugs, I can tell you for a fact that every one of them only made my symptoms worse.
I didn't really begin to learn to adapt well until I stopped using all of them.
I will say that I totally understand why others with Autism who do use them, say that they help. I thought they were helping me too. It wasn't until I stopped using them that I fully realized the detrimental effects they were having while I was using them.
All the drugs really did was masque the underlying problems. If you can't see them or feel the problems, it's easy to think they aren't affecting you. That's what the drugs did, and all they did. They buried the problems that were still there, creating a "mind fog" through which I could not see the problems, and so believed they were not there.
Once I quit, and detoxed for several months, it was clear that every problem I had before I started doing drugs, was still there, and in some cases, even worse because I hadn't been learning to truly deal with them.
Painting the windshield on your car so you can't see the traffic doesn't make the traffic go away. It's still there, and not just as much of a problem as before, but a worse problem than before, because you have no way to avoid it.
What really woke me up is a different analogy, that I actually experienced in real life. Twenty years ago, I moved out of my home town. I thought that by moving away from all my drunken drug addicted friends, I would be leaving all my problems behind. I learned a truth I had once only heard, but didn't really appreciate until a few years into living in a new town, where nobody knew me. This "truth" was one of Jack Handy's "Deep Thoughts." (Anyone remember him from the old SNL's?)
"Wherever you go, there you are."
I thought it was just funny at the time, but once I moved away, after a couple of years, I understood it. No matter where you go, and what you leave behind, you are still stuck with YOU, and all the problems that come from just being "You."
Quitting drugs was a lot like that. Once I quit, I was left with me. The real me, not the fog-enveloped persona created by drug induced fogs.
Self-medicating is NOT the answer.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
