Yep, when your body stops metabolizing alcohol as its primary energy source, it violently protests that change. Alcohol is the perfect fuel, a jet stream of toxic sugar right into our blood stream, and our bodies don't like it when the party is over. Hang in there Icandothis. Your physical symptoms are nearly universal in some form and if I can recover from it, so can you. Hang tough. And you never ever ever have to feel this way again.
