“I've tried various antihistamines but needed something a little stronger for a short period. The advice in the insert is not to take for more than 7 days. This can also be used as an anti-nausea drug for travel sickness. A few hours after taking it at night, I was very drowsy and slept very well that night. I woke feeling refreshed and not drowsy. I haven't sneezed all day, my eyes aren't itchy and my nose isn't running.”
