Sounds like you might want to use your sober time, however brief you plan for it to be, to find other ways to 'reward' yourself that wont kill you. I used a lot of excuses to keep drinking, too. I was being so narrow minded.. but I didn't really know any better. I have no idea if alcohol was causing me health problems, I'm sure that it was.. but I will say that I've never felt better than I have since I've been living sober.
I'm not sure why you're here, we're not too good at supporting active drinking choices. Three doubles? That's three times the 'moderate drinking' amount for men... and a lot of liquor!
Maybe for the 5 days you're sober, you'll find some good stuff here to inspire you. Or you wont, and you'll keep drinking and destroying your liver, which is of course your choice.
I said "I wont drink tomorrow" for so long, it almost killed me. Until I started saying "I will not drink today" did things begin to turn around.
