Morning shakes, retching and/or throwing up without drinking or eating anything or when trying to swallow anything, all kinds of symptoms were my norm for the last part of my drinking career (I had these and others on and off for several years before I quit- they kept getting worse). At some points, I couldn't even sign my name. Drinking more was the only immediate cure......stopping completely was the only true cure.
It is scary to take the leap and quit. Getting all the help you can makes it easier. You can do it - I hope to see you around.
