allergic rhinitis
"Took it around 6:30am before leaving for work. Experienced Terrible insomnia even though I took it early in the morning. Couldn't stay asleep more than three or four hours. Awful stomach pain and loss of appetite. Some itching. Weakness and dizziness when standing too quickly. Dry mouth so I'm constantly drinking water. Unfortunately the other OTC medicines didn't work as well as this product. I'm in a lose-lose situation."
