Welcome to the club! Sucks to have to say we are alcoholics but it is freeing all at the same time. Best thing I did was say it to my husband and he has been my greatest support.
You will probably feel crappy the first few days but that does go away. Drink plenty of water, eat, rest....and if that addictive little voice in your head tells you that you feel crappy, whynot drink anyways-remind yourself that what you are going through right now is temporary and will pass.
