Nasonex side effects

Happened to come across web site written by allergy sufferers or a family member of allergy sufferer (like for their child) concerning side effects of Nasonex.  Wow!  I have this drug but kept forgetting to use it.  I didn't use it and Monday night slept 10 hours, like I haven't done in a very, very long time.  Used Nasonex Tuesday because I remembered it, and Tuesday night, I fought for sleep.  Wednesday night, did not use Nasonex all day, slept from around 10:30 p.m. to 8 a.m.   Used it this morning and now wondering what kind of night's sleep I will have.  I have started feeling more clear-headed.  Not foggy.  Nose hasn't been running.  Was outside quite a bit today.   Of course, now that I write this I sit here sneezing.  My question would be, are the side effects from taking a steroid like Nasonex worth using it?   I'm hesitant to use it at all, feeling that if just taking Singulair and Zyrtec will help, why use more?
