I was a part time alcoholic one time. But I persevered and finally became a full time alcoholic. Then I wanted to prove I was better than everyone else - I tend to do that - and I started being an alcoholic putting in a lot of overtime. I was doing the work of two or three alcoholics. Fortunately I was able to quit before I achieved legend status. But I was on my way.
My recommendation is that on the days you don't drink, continue to not drink. On the days that you would drink, figure out a way to stop drinking on those days too. That should cover it.
