Help! Sick right before baby comes. What’s everyone doing to rid third trimester congestion? [on]

Hey everyone. I’m 36 weeks and on top of having insomnia I now have a chest cold and severe congestion. I read that congestion is common in third trimester but I can’t breathe when laying down and it’s really impacting the little sleep I get. I know we can’t take meds so what is everyone doing to help with their congestion? I’ve been taking hot showers and trying to inhale steam but it’s not really doing anything. Wahhh. SOS.
