OH yes, it drives me mad, its like having hay fever all year round, some days I am ok, then I can wake up blocked nose and sneezing all day, I think its called allergic rhinitis and it makes my life a misery, i have noticed that being in a smokey atmosphere triggers mine off too, so if i have been in a pub or club i can guarantee next day i will be sneezing and blocked up. The only thing I am finding help is taking the drug 'Contact' which can be bought OTC, i have been prescribed steroid nasal sprays etc but they dont touch it either.
