One glass? If any of us could randomly have one glass of wine and walk away not wanting more, we probably wouldn't be here. This is how sick the addicted mind can be.. a reward? For sobriety? What?? In what universe does that make sense..
NOT everyone relapses. Relapse is part of active addiction, not recovery.
I promise you wont wake up on Saturday morning thinking "wow, that was just AWESOME that I had wine last night, I'm so HAPPY with myself!!!!".
And then what? Another night, might have 2.. another you might just blow the whole thing and get wasted.. and we might see you back here asking for some guidance in a few months after you reached another 'bottom' god forbid. The cool thing here, is that you can prevent all that. One glass of wine.. would it really taste THAT good?
It's your choice, we'll still be here either way.
