I have only been sober 12 days but I have been clean from other drugs for a year, Xanax and cannabis 42 days but sober from everything 12. Don't let your slip discourage you, just pick yourself up and keep going. Easier said then done but 3 years is a long time. I am encouraging you to stick with sobriety. When I relapsed April 30 I wanted to throw in the towel but I thought ofmy life and how unmanageable it had become. I'm going to stay sober this time or die trying.
It is really hard for me as all my friends and family use one thing or another. I'm alone in my sobriety that us why I got on this forum and post 2 or 4 times a day. This is my only source of being with others in the same situation. I have tried to call other sober people but no one has called me back. I'm glad I found this support system or I may be drinking or using again.
