On July 26th, 2013, I entered Duffy’s after detoxing. Thanks to the good foundation I got here, I am still sober! I hope the first Monday’s activities are checking out what meetings you will go to after you leave Duffy’s. I am still going to the ones I wrote down 5 years ago. Thanks for being there for folks like me who could not stop drinking.
