Everything Vivian said. And especially with the vitamins. ARE you taking any?
I wish I had some easy answer for you, but you are right: it's hard. Try to focus on the positives. You're still down 133 lbs from where you were, which is awesome!
Have you tried going back to the basics and just making some simple changes, maybe concentrating on eating protein first and not drinking with meals? Then after you've mastered that (and that alone will probably get you started losing) you can work on counting carbs or eating only whole grains, fruits and vegetables after your protein - whatever worked for you in the beginning.
Can you do physical exercise? Even walking 10 or 15 minutes a time or two a day to start out will get your metabolism going again as well, and you'll feel better about things too if you get some fresh air and get your heart rate up.
Sometimes it's hard just to get the bad carb addiction put back at bay. Personally, I'm starting the 5 Day Pouch thing today (I don't think of it as a "test" as much as just re-setting my pouch). That seems to help get the cravings under control for a lot of folks. (I'm using the plan at http://www.5daypouchtest.com/plan/theplan.html
And the alcohol is just empty calories. There is nothing inherently "bad" about it of course, but if you are recognizing that you are drinking too much it's probably time to put it down for awhile. If you need help, Vivian is right again. AA is awesome. (For that matter OA is pretty helpful to some folks as well).
Best of luck to you. PM me if you want to work on the 5 day thing together this week. I could use a buddy.=)
You can do this. You can do hard things. Remember?
