I used to, as part and parcel of being a sixth former haha. But then I realised I was gaining too much weight and was overweight and although I didn't really look it that much, I was aware of it and that's what counted.

So now I try cutting the crap as much as often. And hey, you can still enjoy quavers..which have less calories in them than some special K products. I know which I'd rather be consuming u_u.
