The moral support here is fantastic. I find it helps just to know I'm not a freak or weird or alone in all this.
Get some nice healthy non alcoholic drinks ready for 6pm and every time you take a sip, think about how much good you're doing to your body rather than how much harm. And then before you know it you'll start to like yourself rather than the opposite. See every sip of a non alcoholic drink as a soothing, loving stroke or a hug for yourself?
I've done the self loathing thing for so long. It's exhausting, I'm giving myself a bit more love these days and that's easier if I don't drink.
