I would be very careful. Every couple of weeks I go over to the next town, to have lunch with my Dad at a local restaurant there. He has a couple of beers, but I never do as I have 3 buses to get back home and didn't want to be stinking of alcohol at mid-day on the journey.
Past couple of times though, I've had a 'few' (to say the least) as soon as I got home
I'm on day 16 again and meeting him tomorrow for lunch and am aware that the 'urge' might appear, so I'm changing my routine and going to visit friends afterwards.
All i'm saying is - be careful - it's easy to cope without at the time, but when the stress is over, you might drop your guard andd have a few dangerous moments
Good luck with it though - you can do it!!
