Kindeyes, No advise here, just my experience. The last time my daughter was in rehab, a counselor came around & was talking about SL.....my daughter wanted NOTHING to do with it...I on the other hand thought it would be good. You see we had already taken her back in after rehab stays before and it NEVER worked out. Well, the Sh!t hit the fan and my daughter & I got into a huge fight and I said goodbye & left. She then proceeded to leave the rehab. (Had several weeks to go) Lived on couches, then the streets..........you see she really wasn't done yet..........about 3 months later she found she didn't like living that way anymore and has been clean since. She has a great sponsor who never gave up on her and who would even call me and tell me NOT to let her come home because she felt my daughter needed to face the consequences of her choices.
I know this doesn't really answer your original question, just thought our collective experiences are helpful.
Hugs,
Chris
