Welcome Peppy. I work from home full time around 2 kids. Like you I had a professional career before I switched to accommodate kids (we can't afford for me not to work, sadly).
I just wanted to give you some encouragement. I'm new to actually quitting but my kids are home over the school holidays (one is still tiny but his daycare doesn't do school holidays). I am having such FUN with them. If I was hungover I'd be faking cheerfulness instead of the real deal...and faking enthusiasm and energy too!! So I'm sure you will get a lot of good advice from experienced sober-lifers, but I'd just like to chip in that fun with kids is right up there as one of the best reasons to go for it! I have also been putting alcohol money in a money box when I've conquered an urge and it really adds up, even though I wasn't drinking extreme amounts. I was (am, I suppose, it's early days) more of a binger.
Best wishes to you!!
