Welcome!
It's a good idea to get medical help to get thru detox, which can be dangerous. Ask your doctor for help in getting thru withdrawals. Once you've detoxed then you can look for support in staying sober. SR is a great source of support, as is AA and the many other programs of recovery.
Glad to have you with us.
I quit drinking for good with the support of my counselor and this site. It's been working for well over four years now.
