Creative alcohol avoiding ideas

Hello!

Christmas is coming and so are the christmas drinks at work, glasses of wine during christmas dinner and a little bit of Jagermeister for warming up after a cold day outside... which I used to love, but off course don't use while TTC.

How do you fellow TTC'ers react to co-workers, friends and family members asking 'Why don't you drink alcohol? That's unlike you!'. (I don't drink a lot, but during festivities or family gatherings I have a glass of wine)

Our family lives far away so we stay overnight and don't have the drink&drive excuse...

Have you thought of anything smart to say without revealing the real reason why?

Love to hear some ideas!
