I finally told my sponsor about the pot I smoked. He hasn't told me to change my sobriety date, but he hasn't told me not to either. Alcohol was my DOC. I haven't had a drink since April 13, 2014, and I don't want to start now. This may seem strange, but I don't feel all that guilty about the weed. I didn't drink or do any other substances, and I don't see it as much different than smoking a cigarette or drinking coffee. Maybe I'm just rationalizing it, but I don't know if I really blew my sobriety.
Today is the first day I'm really sharing this with anyone - including my sponsor. I needed to get this out in the open rather thanked it secret.
