I have severe allergies atm (yay spring.. not!) And one of the side effects is post nasal drip.
Because my breathing was so badly affected I'm on a 3 day course of steroids, symbicort (sp?), and ventolin as needed. I have also been given the OK for antihistamines, decongestants and cough medicine that helps with nasal stuff.
The drip is all very thin and I can still breath through my nose, but I can constantly feel it dripping down my throat and it's making me cough cough cough!! Only at night too! All day long I have been fine except for the occasional cough here and there, but as soon as I went to bed, Bam! The coughing started.
I have currently filled my quota of all the medicines I can take and so far nothing has helped!! I am still awake at 2am desperately tired and exhausted and have to wake up in 4-4.5hrs when DD wakes. And I know once I do fall asleep, these meds will zonk me and I'm going to be super exhausted because a couple were drowsy meds.

Anyone have any suggestions on things that help PND?? I'm getting super desperate

Sorry about the long windedness, my brain can't make it any shorter in my sleep deprived state
