I hear ya' on going "public"--I posted a pic over in the "Success" thread of me "before"--not pretty and I had almost another year of weight gain added to that picture. Let me tell you I had to work up the nerve to post that, but it is what it is (or was).
A year ago it was truly all I could do to walk 100 feet so I have a feel for where you're at. Today I jogged 2 miles in 25 minutes.
Even with minimal/no exercise I think you'll see the weight just peel off if you keep a really big calorie deficit. Just like you, I quit the junk, I quit the daily 6 pack or 8 oz of vodka and just switched to 1500 cals a day of good food.
Don't ever hesitate to post if there's anything I can do to help. You can even email me if you don't care to post here in "public" at firstname.lastname@example.org
