Hi Mia1972
You have to be realistic about it really. You don't drink so you need to just keep saying that you don't drink. Once people hear it enough times they will surely stop asking you and the topic of conversation will shift.
The major question is really within. Can you enjoy yourself as you travel to these places without drinking and will you feel at ease. If you cant or you are not ready for this just yet then i suggest you avoid going there until you are further advanced in your recovery. Its not a good idea to place temptation in front of yourself unnecessarily. Wait until you are ready and that will come with time and experience.
