I'm like Itchy - further along, so I've dealt with it for a few years. I remember the first sober one, though. I cried & was sorry for myself. I couldn't have "fun" like everyone else. Back then, I still thought I was missing out - as if something had been lost, rather than gained.
I think the first year after we've quit has many hurdles. Holidays, birthdays, vacations, the change of seasons - all loaded with triggers. I know you read it all the time on here, but it does get much easier as you go along. I look back at my drunken holidays and wish I could go back & experience them clear headed, not numb and in a fog. You're doing great, FlyingRight - be proud - and know that it won't always feel this way.
