I should have been specific. My problems were with crystal meth. Stay away from that bad boy! The thing I miss is 'E'. I know that's not exactly the same as MDMA, but often make the mistake. Never had much problem with that, other than some fairly unproductive days following usage and annoying comedown. But I certainly wouldn't advocate it either. I never overindulged with that one. I recognise there's a fine line between using a substance in a controlled way, and the using/substance controlling you. From my little knowledge, that's all mixed up and dependant on the chemistry of the substance, your own circumstances and state of mind, (or vulnerability) and the amount or regularity of using.
I'm glad you sound as if you're dealing with things. I'm equally concerned you're not getting other help. There's far smarter people than you and I, who have got sucked into a wrong direction, so there's certainly no shame in asking for help. I'm someone who's always had to do things their own way, and never ask for help. I've learned the hard way that's not always the smartest choice. I don't know where you're from, but there is councilling or support groups available in most places these days. Joining here has been a good step, as at least you will find people to relate to and share with. And you've got me as a friend now as well...god help you!

BTW, I relate to the bit about trying drugs again. From my previous post you'll see I've still got that slight itch. Being someone who could handle things for years, as a very casual and infrequent user, to going to someone with a problem, does make me worry I might go loopy again with the slightest indulgence. I definitely wouldn't go near CM again, and there's lots of other stuff I'd stay clear of, but can't honestly say stuff I've handled previously, without significant consequences, is unappealling.
What's P*L*U*R - I'm out of touch!?
