Hi and welcome.
A similar story from me too. Drank too much when younger but thought nothing of it, then quit when pregnant and my kids were little, only to resume when they were out of sight.
For me it took years but became steadily worse as they grew up and needed me less on a practical level. Now they are teenagers and lead semi independent lives and that's where my problems really escalated.
I wish I had had the courage you have and tackled this earlier but better late than never.
I have accepted I'm an alcoholic after all attempts to moderate were unsuccessful. I've quit completely and am beginning to discover a new and much happier side of life. That guilt you struggle with? Well it disappears!
Keep reading and posting, this is a wonderful place to start! Xxx
