Sudafed, why aren't you hooking me up?!

I just got Max to sleep and was hoping I would be able to get some rest soon as well, because I took some Sudafed an hour ago, but I still can not breathe!!! We have had the sickies going through our house for the last week and a half and it finally caught up with me Sunday. But unfortunately I am only able to take Sudafed (because I am still Max's food source) which sometimes is just not strong enough to get any relief. I HATE colds!!!
