I get uncontrollable sneezing attacks that last 12-24 hours. My symptoms are constant runny nose and sneezing, which leads to me getting very tired. When I take a nap I start to feel better and by the next day I m back to normal. It happens every couple of weeks. I have tried flonase, claritin and Allegra D and non of them help. The only thing that seems to help is ibuprofen and sleep. Could this be due to lack of sleep?
