Anyone wake up starving at 1 a.m?

Question

For about a week now I've been waking up to my stomach growling around 1 & 2 a.m. It's so empty that I feel nauseas. 
I eat a snack before bed & I am full.
Anyone else having this problem? 
I already have enough trouble sleeping,I want to fix this! 
I'm 7 weeks.
Thanks!

Answer

My first pregnancy I woke up almost every night hungry. This time I am occasionally but not every night. I try to drink some water to help with the hunger pains.
