Anybody know what I can do or take for sinus congestion. It's been 4 days already and I'm in so much frustration and all i want to do is cry. It has gotten to the point where I don't sleep at night at all cause it's so hard for me to breath with a stuffy nose. I end up going to sleep at 10am everyday and just sleeping 3-4 hours. It freaking sucks having to chase a almost 1 year old around and being 27 weeks pregnant. 😭 I just wanna sleep!! Please help!
