Hey there, welcome back. I have to be honest, I too had wondered many times if you were still around. I wonder if that bothers you to know that many people figured you had probably succumbed to your addiction and died? That is really very sad and scary! That's some really crazy stuff!
I'm glad to see you are still here, and I'm glad you're trying, and I'll repeat the great questions you were asked.....what are you going to do different this time? I want to post a link to the last thread you started here, almost a year ago....

I would recommend reading it and rereading it. One thing I'll give you is that when you set your mind to it, you give it he**.....but you have totally neglected ever following up with a long term plan (aftercare), you often fail to cut your sources, and put roadblocks up for yourself. You focus on GETTING clean and that's where it ends for you, which is why you're a cyclical relapser.
You've been doing this a LONG time, and pretty hardcore. SOMETHING has to drastically change, you know that, we've told you that before. This IS a life and death battle. This time simply HAS to be different for you, or it will likely just be more of the same....the merry go round, the cycle. Your body is only going to take so much, and you've already done some damage I'm sure, especially with some of the drugs you used.
I'm so glad you have a great new fiancee in your life (is she the same one you talked about in the thread I linked above?)....you have a lot of incentive to get clean, to be the husband and Dad you KNOW you can be.
As always, I wish you the very best.
