I too have been on the "my husband's addicted to cocaine diet". I've lost 17 lbs in 6 weeks! That is the ONLY good thing that has come out of it!
Sorry, but I doubt I will ever complain about losing weight. I wasn't overweight before, but what woman doesn't want to lose a few lbs? My husband stayed "slim", but he is a huge guy anyway (6'4" about 225). He is 38 years old and has never had weight issues. But he never got rail thin either while using. He just stayed about the same. He was using almost daily towards the end, so I guess he made up for times of not eating on days that he didn't use? Maybe their body gets used to it? Heck if I know.
