Hi Khloe, I think everyone has nerves when quitting. Whatever the job. Remember why you want to quit. Stick with it. The nerves do calm down with sobertime. Best wishes.
When people drink, alcohol is a depressant. So the serotonin, dopamine and other "feel good" responses overeact in the body to compensate. When you take away the depressant, they are still overeacting for awhile. This makes the high nervous energy. In time, your body adjusts.
