Ok, I'll throw out this at this point:
Post successfully handling an event sober, I learned from Dee a long time ago that it is wise to be proud we did - and it's wise to temper that with any blase (/) attitude or over confidence that can creep in.
Further, I'd ask you what your plans are for the coming work week? I was also told early that using an outing as less a chalkmark in the plus column of victory than a springboard to navigating our next "event" sober.
I'm quite concerned about how you are doing but do hope for the best. Glad you are sharing.
