The best bet for anyone is to see a Dr, Slayer - for some of us detox can be dangerous...at the very least your Dr may be able to prescribe something to help get you through it without you having to revert to drinking.
Similarly, with long term damage - ask your doctor for his or her assessment of your particular case - noone here can answer that for you.
But I do know the sooner you stop, the better chance you have of no lasting damage - many members here have recovered fully
