There aren't many better excuses to give up m8,
I wish i could give up sometimes for pretty much the same reasons - it makes me lazy, moody, and i care less about the way i look etc....
although i am single, so i don't have anyone badgering me about it,
but i do really enjoy being stoned, there's nothing better than a saturday night getting drunk with my headphones on, listening to my favorite tunes with a dirty big spliff in my gob
though this probably explains why i'm single

good luck
