You should definetly stop drinking altogether. You might be amazed at how much progress you make.

As far as the other problems... you just have to stop it. You know and feel its wrong... so don't do it. If you have the ability to understand a thing is wrong... you also have the ability to correct it.

The reason you do these things is because you allow yourself to do them. You can't go on thinking that your illness has some sort of supernatural power over you. It only controls you because you let it.
