Squishy,
I like your start in that you already pushed your excuses aside and have drug addiction experience to fall back on. What are you thinking will be your recovery plan aside from here? Obviously your spouse knows about it, but your kids will have little recollection if any if you stop now. That is a good thing in that they won't have memories of you as you mentioned you have of your mom. You are in the right place, at the right time, and have everything to quit for.
We will be here for you.
