Each relaps and detox can get progressively worse, but sounds as if you nipped this one in the bud today, right? You are here and not drinking - that's what matters most. Just about all of us have relaped multiple times.
You CAN quit and you WILL if you really want to. What kind of support are you getting locally? Perhaps it's time to ramp up the committment to both local help and SR? Best of luck and stay with us!
