Hope you´re feeling better soon.
One thing my neighbour has recommended to me in the past for a stuffy nose, is to put some honey on a cotton bud and wipe it around the inside of both nostrils - sounds disgusting I know, but at the time I wasn´t even pregnant and over the counter stuff just wasn´t doing anything for me. I tried it out and that was the first proper nights sleep I had, didn´t wake up once due to my nose being blocked. Apparently honey has some kind of eosotheric (sp?) oil in it, that helps clear the nose. I do this all the time now whenever I have a cold and it really helps. Its a bit gross when you blow your nose the next morning, but a good nights kip is more imprtant!!
Another little remedy I´ve picked up from my neighbour is if you have a very bad cough. Chop up two large onions, stick em in a bowl and cover them with about 2 inches of sugar. Cover the bowl and leave for a couple of hours. After a while, the sugar dissolves into the onions and you get a bit of liquid in the bowl. Keeping spooning off the liquid and take as many times during the day as you like - again it sounds gross, but the liquid doesn´t actually taste as bad as it sounds, quite sweet really. We had friends staying wth us and their little boy had a really chesty cough, we gave him this stuff and the next day there was a huge difference in his cough.
