Yeah, I sleep mostly on my side with a pregnancy pillow between my legs. But my problem has been drainage of mucus down the back of my throat. I don't normally have allergies but I have had a runny nose since we moved into the new house. I don't know what the deal is! As soon as I lie down, it terrorizes me the whole night! MW had no good suggestions for me. Said a neti pot or benadryl. I can't take benadryl every night and I'm scared of the neti.
