I went to an inpatient rehab for 6 months a couple years ago, drank again a month after leaving. I don't regret that now though, I see it as part of my journey.
Am now sober 6 months ODAAT, through AA. The gratitude I feel for the fellowship and the program is immeasurable. If you had told me 12 steps to get a power into my life and a design for living that works, I was more than sceptical even though I was dying (insanity!)
But it took me being on my knees and willing to do anything to finally accept my alcoholism and take a good look at myself. A daily reprieve, and the journey is only beginning. Amazing
