Nighttime 'Feed me' rant!

Alison • Pregnant with baby #1. Due mid-November. We conceived after our first attempt of donor insemination.
FTM @ 10 weeks. Sleep is super important to me as I am unable to nap during the day. However, I've noticed the last couple of days that unless I stuff my face right before bedtime (9 pm), my stomach wakes me up between 3-4am as if my throat has been cut. I'm talking full out 'Feed me or I'm gonna die' hunger. I hate gorging before bed but I equally hate waking bolt upright and having to go make make myself a sandwich in the wee small hours of the morning. It's 6 am and I've been awake for 2 hours when all I want to do is sleep! GAH!!!! Sorry...just wanted to get that out!
