A big problem with alcoholics is that when we are drinking we dont eat. Drinking on an empty stomache just tears the lining up.
Im no expert, but I think you should atleast TRY to stop drinking before you address the eating and sleeping issues. eating will come back slowly and sleeping well that takes a little longer.
I would like to make a suggestion about your diet. If you can only hold down small amounts of food you might want to try to eat things that are healthier than hotdogs and fried foods. Try some fruit and veggies they are vitamin packed and vitamin depletion is also a big problem with drinkers. Plus you might find they go down easier. The fish is a good thing, but try to have it baked. Fried foods are hard for anyone to take especially those with stomach problems.
