Well, for a 2 bowl daily smoker, 20 macs, 2 bleach & redyes, and two zydots, along with numerous other washes with tide, aloe rid, and other cleansers, and 16 days clean. I got the call I didn't want today. I guess the only thing that is a guarantee is not smoking. What a bummer,I really wanted that job. I don't blame anyone but myself, and appreciate all the help I got, but hopefully someone else can learn from my mistake. Damn I wish it was legal.
