Ahahaha i have waist-length hair as well, and well, I've always wondered how much Id weigh without it..! Usually when I weigh myself, its after I get up and pee and hopefully crap.. nod..

What I'll do is, after I get up, I'll get on the computer for a little bit and let myself wake up.. make sure theres nothing in the bladder and such..then, before shower, before diet coke, I weight myself.. usually 3 times, sometimes 4, (in a row) cause my scale always gives a different number.. then I'll take the number that showed up the most and use that one as my weight..
