Well, I'm sure some will advise you not to lie. But in my case, if I felt that uncomfortable telling people, I would just say something like, 'I am off the drink because it hasn't been agreeing with me lately.' Which isn't really a lie, or something similar. Enjoy your hols. I have had many sober holidays and they were great. Hangovers in the sun are horrible. And it can be quite hot in Feb over there. xxxxx
