Welcome to the family.
Itching is one of the symptoms of withdrawal. If you stopped drinking, that might be why you're itching. It goes away the longer you are sober. If it is worrying you, see your doctor for blood tests of the liver. That can put your mind at ease.
You'll find a lot of support and useful info here. I give SR a lot of the credit for my six years sober. I hope we can help you as well.
