Try this as well for what they can do to you...

I have suffered from eating disorders and know the harm they can do to you, it's really not pleasant and having spent a number of periods in hospital and gone to hell and back (and probably put other people through hell) trying to get myself better, part of which has included trying to kick an addiction to laxatives and the like it's really not worth it to lose a some pounds.
Think how horrible a stomach bug is, the runs, big time, often uncontrollable stopping you from doing anything, stomach cramps, feeling horribly sick, being dehydrated then either risking dehydration and potential death or having to eat and drink to keep going and bloating up and messing with your metabolism so you're worse off than you were in the first place.
Whether it's for you or anyone else hon, it's just not worth it xxx
