Your story sounds very similar to mine!! I am also a wife with two young kids (3 yrs and 6 months). I used to have a bad coke problem before I moved away from my hometown. I dabbled a bit here and there before my kids were born but I had to stop. I love it too much. I can't stop once I start, I will do it all night and the thought that I wasn't in control enough to stop scared me because I feared overdosing, dying and leaving my babies without a mommy. That's the ONLY reason I don't pick it up anymore. But I replaced that with alcohol and that it what I am battling now. I do the same thing with drinking and I don't want to live that way anymore. You have made the right choice by stopping both for yourself and your family. It's a nice feeling to not feel guilty after a weekend of partying. I drank too much AGAIN over the weekend and hate myself for it. I'm sick of hating myself.
Good luck and keep coming back.
