I am not technically sober but I stopped drinking mostly. I was at 225lbs and beside the food I drank a bottle of wine every night and Drinks throughout the week. Mid January I decided to quit sugar. Obviously that meant the Booze too. Full disclaimer, I had wine with Easter and will next week with my Veal Parm dinner at Chef Volas in Atlantic city.
But aside from that not drinking. Feels great and when I did have wine for Easter I had no interest after the second glass.
As for quitting sugar, its a game changer. After 3 days you have no food cravings. Currently at 175lbs and feel amazing.

Its all about insulin response. The hard part about quitting sugar is realizing that we are being pumped full of it in everything. Honestly its hard because its an effort to avoid. Its shocking how much is in almost every thing. The easy part is once you stop doing it yourself you happily avoid it.

Truth!!!
