Maybe wrong sub? But how do you guys keep yourself from binge drinking

I wouldn’t consider myself an alcoholic though I have alcoholism definitely, I’m a 21 year old male, 6”1 245 lbs and I drink on a weekend basis. I can go awhile without drinking but when I do have a drink it always escalated until I’m drunk.. not until I’m blackout wasted but every time I drink I get drunk. How do you guys set boundaries?
