Hi Emily! I know exactly what you mean because that is how I am. I could take or leave alcohol most of the time, but when I do drink, it gets baaaad. Not every time, but often enough. And after going back and forth with quitting for about two years now, I can tell you it only gets worse. I had to cut out drinking entirely, because even though I was only bingeing on the weekends (and not even every weekend) the impact it was having on my life was felt all the time. Mistakes I made, things I said, hangovers that were getting longer and more intense...
This site is great. I am not an AA person, although maybe one day I might be. Going to meetings can be a good use of time to distract from drinking. And what Anna said, MAKE PLANS. Sober plans, of course. I have to, especially if I know my friends are out partying and I don't go with. It's easier to decline now, as I am just older and not as into it as I used to be, but I still get antsy knowing that my friends are "having a good time" (if you can call it that) and I'm not. So if something is coming up that I know I shouldn't take part in (even things I am not at all interested in taking part in) I HAVE to make plans to do something, even if it is just a conscious decision to stay in and watch a movie I've been meaning to. Or exercise, or cook dinner or anything really that doesn't involve drinking.
This forum is a great asset. Sometimes if I am bored or antsy, I just come on here and read and respond to posts. It strengthens my resolve, reminds me why I quit and makes me feel better being able to contribute to worries others have about their own problems. If you ever want to talk or air your concerns, post here or you can PM me. I know all about weekend binges
but I am trying to not be such an expert. 3 weeks today and you'll be there soon!
