At one point I stopped drinking and went through a horrible withdrawal (alcohol and klonopin). It was so bad that when I got to 2 weeks and it was still pretty bad I decided to stop, at least for awhile. I was living in a party house, my roommate drank himself to death several years later. But I was so disgusted by their drinking I had no issues staying sober. Wish I'd made a permanent commitment at that point, but I didn't drink for over 7 months, and when I did start again I drank relatively normally for a few years after.
It is possible.
