Go for it Love! You can do it!
I had a similar experience earlier this month around my 60 day mark with my annual golf trip down south. A big drink fest with the buddies but I maintained! I really felt confident on my return that if I could make it through that, I could make it through anything.
Wine country rocks! Concentrate on the beauty of the area, the interesting aspects of the business of wine-making, people watching and enjoying sober life.
You can do it!
