Flonase
"Flonase SUCKS. The first two days I used it, I thought it was the greatest thing ever invented because my horrible allergies finally seemed to clear up. I forgot to take it one day and woke up in the middle of the night with a stopped up nose, so I took Flonase again as soon as I woke up. It was VERY ineffective that time. I got horrible headaches, insanely itchy eyes, a sore throat, and my mouth and lips were constantly dry. It has been a week since I've vowed to never use Flonase again, and I STILL have the WORST smell in my nose and mouth from that stupid allergy "reliever". If you're wondering if you should hop in your car, make the trip out, and purchase Flonase, I will let you know right now that, that is the biggest mistake."
