BigSis, I love what SpiritualSeeker said, "Relapse is a symptom of addiction"
I remember when I used to drug. I went to rehab got out and within a week I was right back at it. But, it didnt' last long. I relapsed. A very short time later I thought about how I had spent that time clean and it actually felt better than high.
I moved away from it all. I never touched it again. That was 30 years ago.
I hope that her wheels are spinning in that direction. That sober feels better than high.
