I can't believe I'm doing this...
Ok Mike, if you're reading - your first step is AA. Drop whatever you're doing, and find your nearest chapter and attend the next meeting. It's going to feel awkward as hell, but it's what you need to do. It's going to be rough.
After a month or so of attending meetings, you need to find yourself a good psychologist/psychiatrist specializing in addiction. Penn's got good ones, and I'll even recommend a few names if I can find ones I'd trust.
If you're serious about getting help, then we can help. You're not going to be able to kick "this" yourself.
