Sleep issues

Jenna • Baby no. 1 due March 2016!
I am 20 wks 4 days. Haven't slept well since entering my second trimester. I have always been a stomach sleeper and have finally trained myself to at least get a pillow under my belly and between my legs. I have a snoogle which helps but I am still not sleeping restfully. Hot flashes have also consumed my sleep. It's driving me nuts!! Am I alone or is anyone else having trouble sleeping? I'm afraid of what the third trimester has in store for me :(
