Midnight Snacking

I would love to be able to sleep through the night every night (which would mean giving up drinking anything after 4pm which leads to nighttime bathroom breaks.) But some nights, especially when I need it most, I either can't get to sleep at all or I wake up because of a sound outside and then can't get back to sleep. So......what do I do? Reach for the candy!!! Are there any other midnight snackers out there? I could be exhausted and just want to lay in bed, but once I'm awake I feel like I need to check out the cabinets and refrigerator just in case there's something miracle snack that might put me back to sleep!
