Congratulations on 60 days... that's fantastic!!!
I agree with Laurie6781, you don't owe them an explanation. Continue working on yourself and your recovery.
I relate to you in the fact that for years i said I was going to quit, slow down and never did. So I too needed to prove to myself first that I was serious about quiting. I didn't say anything to anyone... my friends started to notice a few weeks in and started questioning me. A popular one was NEVER AGAIN Shannon? Of course that's my master plan, but shocking to their ears to hear. I'm doing this for me, not them.
Most of my friends are very supportive now... It's been over 4 months since I have drank the 'poison'... and I could not be happier or more proud of myself!
Good luck my friend!
