allergic rhinitis
"I used this for hayfever when I was 17 and it made me drowzy. I'm now 26, have suffered from insomnia for many years. Recently, I remembered about these making me drowzy as a teen so I decided to buy some in the hope that they'd help me sleep. They didn't really do much to help; they might have made me slightly more drowzy but they no way had the same effect on me a 9 years ago."
