about three days. that's shocking.. it didn't help that i bought them at totally the wrong time of the month, but they tasted so much like something-that-i-can't-eat-but-want, i just went nuts. they don't taste any better than any other protein bars (i got the marble fudge flavour) but they were still good for the price i paid. i found them here.
as a consequence of my lack of control with them, i've gained 2.5kg, however i also realize some of the cause of the weight gain is because it's 'that time'. it usually falls right back off again, but it'll take a bit longer this time around. damnit. they were supposed to be for my lunches at work too.. heh. i'm going to have to learn a bit of self-control for the next time i buy them.. *hangs head*
