I too advise medical supervision during detox, as it can be dangerous besides very annoying. Drinking lots of water and juice can help flush out the alcohol. B vitamins are also very good. Chamomile tea can help to calm the anxiety and milk thistle is good for detoxing the liver.
Just don't drink today. Take it one day at a time. Once you get thru the first few days of detox you can start to feel better and stronger in your sobriety. You CAN do this!
