Allergic Rhinitis
"I took this at 7 am to try and fix itchy eyes.  So far, 4 hours later, there is still slight itchiness and wateriness. Worse is the side-effects.  I feel slightly jittery, yet mentally it feels like I&#039;ve taken a tranquillizer. I don&#039;t feel I&#039;m safe to drive. Basically if you are a first time user of the 24 hour version, don&#039;t try it on a day you have to use a car."
