My AH went from wine and beer to vodka, and it's definitely a different kind of 'drunk.' He's more aggressive and gloomy on vodka.
It all weighed me down so much until I got involved with Al Anon and SR. Now I can see what there is nothing I can do to stop or help him. I have to care for myself and our children and let him go. Once I experienced that mind-set, the burden of AH's addiction lifted off me and I was able to release him.
If you can, try attending some Al Anon meetings in your area. I tried several until I found one that felt like a good fit. Just a handful of meetings and a lot of reading made all the difference in the world. Hugs to you!
