Hey there, Jjb. Congratulations on day 4; you sound very positive and committed to sobriety and that's the attitude you need to succeed. I don't have children but remember well my dad's brutal alcoholism and how he was not fully there for me as a parent. I know you want your kids to have a wonderful life and to be there completely for them.
I drank only beer but alcohol is alcohol no matter the form, about 18 a day. (I am a small woman.) When I quit full stop I suffered those awful hallucinations and had a couple of seizures as well. It was hellish but I got lots of help (I needed it!) and celebrated my 30th month of sobriety last Saturday. I can't moderate either--I have no 'off' switch when it comes to drink. I was about as far down as it gets--now things are not perfect but they are much better, and that's enough. Wishing you all the best on this amazing, sober journey.
