hmm. well theres plenty of things. try checking health websites.

but me personally. if i crave food at night i go for healthy things.:
water- drink a whole bottle and my stomach is full.
almonds,peanuts,nuts- another good choice
big mac- <img src="/images/graemlins/tongue.gif" alt="" /> haha just kidding . you do not want this!
dried fruit
popcorn-im ify on this, but it has to have nothing on,and air popped if anything.
gum-sometimes just chewing helps
ice- for me it does the trick.sounds weird i know.
peanut butter cracker- im ify on this too. but as a kid it did the trick.
celery-i enjoy it ,a lil peanut butter is good too.

thats just a small sample of what there is. just look on the web and use your head ,you will know whats healthy and whats not.
