That's a big step talking to you supervisor and taking some accountability about quitting drinking. Way to go! After the 7 days will you be able to do some outpatient treatment? If not you might want to try 90 meetings in 90 days. It's not about will power, that runs out eventually. I tried the white knuckling before. My secret now is that I'm to the point where I actually don't want to drink! Much easier/better to stay sober that way.
