I have now gone over 1,000 days without drinking alcohol. I was not an alcoholic as conventionally defined, I drank less than what my friends or colleagues or others around me did. But occasionally I would drink a few too many and not feel well the next day. I began tracking exactly how many drinks a day I had (I did not drink every day), and it was eye opening. I decided to cut down from there and after a few years of trying I eliminated alcohol entirely from my diet.
I highly recommend every person that drinks alcohol track the number of drinks you have on a calendar and rate how you feel the next day.
