sedation
"I found this little gem a few years ago. Whilst in my late forties I had a blocked nose I spent a fortune on remedies and although this sounds insignificant it became a constant annoyance as symptoms were so awful it caused nose bleeds, cold sores in my nose, sleepless nights etc. Eventually I went to the doctor who informed me it was a allergy. Beconase nasal spray and a antihistamine tablet. This I used daily as my allergy didn't subside with the changing seasons, it held it back on a good month although I never had a restful sleep. Then I found Phenergen and since I started taking it just before bedtime all of my symptoms have gone! The down side is I find it challenging  to buy!"
