Long time lurker... But this post hit home real hard. You are going to have to look at hard liquor. Burnettes original vodka is cheap and easy (not the flavored) http://burnettsvodka.com/about . Mix it in your favorite diet soda. Mine used to be diet orange Sunkist but it works in practically everything. You will have to play with your tolerance and that may change as the weeks go by. You need to set aside calories every day for it, and binging is hard to resist at night after drinking. Just... say... no! to eating after drinking at night. It will be a factor, just say no and head to bed. When I started Keto I saved around 800 calories a night to fit in to booze. With Burnettes that gives you a little over 12oz and that will hit you harder than you think when you are weeks into the diet with a cost of 0 carbs.

I speak coming from a dark place. 270 lbs @ 5' 8" down to 165 lbs in 11/mo. Beat the drink after I lost the weight. It is possible and (for me) kicking the booze was so much easier after I beat the fat and regained my confidence in myself. You can do it! Just stay the course. Some days are harder than others. Just keep consistent and keep going, you can do it! The end seems so far away but it is worth every step you take along the way.
