I haven't yet been in a situation where anyone would notice I'm not drinking- I'm on Day 8 today and I have a zero social life so I'm seeing that as an advantage for me. But I do recall an afternoon out in a pub one day last year when I wasn't drinking and it was so awkward! Everyone kept trying to buy me drinks and I felt so conspicuous! It made me feel resentful towards everyone for wanting me to drink with them so badly. It was like no one could understand what was going on- it was inexcusable that I was drinking water! I found I couldn't relax properly or fully enjoy myself either; and I must admit that I'm worried about that for the future when I next get invited out somewhere. I can't imagine going anywhere socially and staying sober. In fact, the thought quite literally horrifies me. So, I'm staying home for the foreseeable!
You're very strong- keep at it. More power to ya.
