Congestion and Insomia

24 weeks today and I feel like I haven’t been able to breathe (especially at night) since before Thanksgiving. I’ve been through two rounds of antibiotics, so it’s not a sinus infection. Other than taking doc approved Sudafed, what else can I do? I’m rinsing with a neti pot, taking Claritin and Benadryl, using Flonase and a humidifier. I tried Afrin one night and it was magic, but i know it’s addictive and I don’t want to use it again. I wake up several times at night and can’t breathe and am exhausted.
