Torn that I gotta find a new beer or quit or cut back

Yes, hard to believe but my choice of drink Is a 4loko. One and im solid. But, that’s the most carbonated and calorie drink on the market. Im finding myself going from 157 pounds to 175 in couple months. I love drinking, hard to not have one after work. But, I don’t wanna get a beer belly. What yall suggest.
