Hi HIgby
I know couldn't be sober and around my old drinking circle - it was as simple as that - but they were pretty much alcoholics...I'm not sure about your friends.
If you're comfortable doing so, I suggest you let them know right from the get go what the deal is.
If you're not comfotable with full disclosure you at least need to tell all and sundry you're not drinking tonight or right now or whatever...
But the other side of the coin is - you've been living sober for 100+ days now - you can do it and you can maintain it - no matter what. Get over the block of not asking for help - ask for as much help as you need.
Keep making those fallback plans, and get a support network in place. I remember not believing in myself too - I'd been a 'failure' for so long. That was alcoholic thinking.The support I got helped me through.
You can do this.
