Eveadel, glad to hear I'm not alone! I've been having a right old time with my blocked sinuses, they've been driving me mad. Like you, they seem to get blocked just as your going to bed. Last night I used a saline spray solution which worked for a couple of hours, however I've just caved in and bought some Beconase nose spray (I used to use it before I got preggers for my allergies), apparently it's one of the few sprays you are okay to use while pregnant - if anyone knows any different please let me know. I promised myself I wouldn't use any medication during my pregnancy but I can't hold out any longer, not having a good nights sleep is starting to take it's toll on me now!
