A few days after I quit I went around to my drinking buddys place - I remember posting here it was important for me to road test my sobriety
I made it out sober but it was a dreadful fraught tense and awkward day.
I never did it again - there's plenty of time for us to live our lives sober and put ourselves in any situation we like - once we get the basics of living sober down.
If your friends already on her way I know you can make it out sober like I did - but set it out straight and clear up front...to both her and you - you're not drinking anymore.
