150ml of vodka a day

The maximum I ever drank was about 500-700ml of vodka a day, for a period of a few months and now I’m down to 150ml. I weigh about 94lbs and don’t eat much so I can get a good buzz from the 150ml and then get to sleep and not be up all night like I am when I’m sober. And I can still keep up with everything in my life. I know it’s not exactly healthy, but is this successfully moderating my drinking?
