I Have A Serious Post Nasal Drip Which Causes Me

I have a serious post nasal drip which causes me to constantly have to clear my throat.
It feels like mucus is stuck in my throat, but I don't spit anything up. I have seen an ENT specialist and he has identified that I have a deviated septum. I sometimes take an Allergy medicine like Zertec to help, but the clearing of the throat is so irritating. Especially for my husband...
