i have had certain symptoms for about a year and a half. one summer i had a stuffy nose and could not sleep. so i used lots of spray in each nostril so that i could go to sleep. it didn't work so i used my sisters nasal spray. i belive i then used another nasal spray. i layed down to sleep but i started to get a lot of saliva in my throat. i had so much saliva that i was drooling all night in my sink that i didn't sleep that night. ever since then i feel like i have something in the back of my throat. i always have to blow my nose every 15 minutes. i think it post nasal drip but i dont know. i feel like my throat is tight and feel like i have to burp but can't. this gets worse when i am sitting in a chair or laying down. but my main concern is it gets worse when i get nervous like when i get called to read in front of my class.  i feel like i am about to choke on my saliva. i have so much anxiety and never want to present projects. i never had these symptoms before that summer when i had a lot of saliva. i really want to cure these symptoms as soon as possible.
