ACK - hide them! lol Ask someone to hide them for you
I haven't had the urge myself to eat in the middle of the night if I am sleeping and wake up - BUT if I'm up late, then I ususally get a nasty case of the munchies - I will usually drink a cup of water or even hot caffine free tea to fill my tummy up.
Sometimes if I wake up and have problems getting back to sleep, I'll heat up a mug of skim milk and add a tiny bit of honey to help me get back to sleep.
You can do it
