Congratualtions!

Could always suggest that you're on a detox following some particularly heavy drinking sessions!

Being partial to the odd glass myself this was also an issue for me. I've tried Tonic water with a slice of lemon in a shorts glass (passing it off as Gin and Tonic) and another good one has been keeping a non-alcoholic champers in the fridge for when friends pop over (tastes nothing like champage but rather sparking grape juice but it's not unpleasant - you'll just need to give your friend the proper stuff!)

Good luck!

Sara.
