15 Drinks over 10 occasions, huh? Well, all I know is when I was still drinking it was pretty standard to tell the non drinkers in my life (or my doctor) that I drank about 20% (at the maximum) of what I really drank. Not saying your husband is lying, but that's kind of what we do when we're not 100% committed to recovery. Take it with a grain of salt. Well wishes to you.
