Congrats on 6 days.
A lot of people don't realize that hangovers are actually a mild form of alcohol withdrawal. This is why taking a morning drink actually makes you feel better - the alcohol is provided so the body stops or slows the withdrawal process.
Of course, this is progressive, and if you are like me it got to the point where I could be on the 6th drink of the day and still be in withdrawal. Thank God I don't have to live like that anymore.
