I have been, 3 times actually. It was easy to stay clean while in there, but I wasn't down with the 12 step bullshit and the meetings sucked. I looked at it as more of a drug vacation by the third time(and an easy detox), cuz I knew it wasn't going to work. At any rate, I haven't used any drugs(besides valium) since January 7th, this time I used Suboxone for three months, no rehab. I wish I could say I was happier sober, but it is what it is. Good luck to you.
