Man, it happens. I can't even begin to tell you how many times I have set a limit on myself with opiates and then broken it the very next day, or at least sometime before I had promised myself I would. God, so many times... it made me feel sad and pathetic. But it doesn't mean you can't just get back to staying away tomorrow (although it's always easy to say I'll wait til tomorrow and that can be a trap). For me, it seems like the more times it happened, the better I got at dealing with it emotionally, so when I finally did quit, the physical withdrawal was the worst part. Eventually I got strong enough to stop using opiates.

It sucks having an addictive personality, particularly when it comes to drugs, but it's all a learning process.
By the way guys, I haven't had a single opiate of any kind for over 2 months now. About 2 months ago I stopped taking loperamide every day or two (it was helping with post-acute withdrawal symptoms and restlessness), which was the last opiate I was regularly taking. Also during that time I was having poppy seed tea maybe an average of once a week, but only once each time. But the last traces of withdrawal kept hanging around until I finally stopped taking all of them. And I don't feel them at all anymore.

I was feeling quite depressed and empty for about a month and a half though, which in retrospect is probably closely related. But I've been out of that for a good 2 weeks I'd say. So I'm feeling good, and it's almost hard to believe that I'm actually totally off opiates completely and comfortable.
