I will never use this product again. I loved using Vicks but this was just disappointing. I sat on the floor of my bedroom and cried for over an hour because the pain in my nose, head and mouth was unbearable. I used the spray exactly as it said and about 5 minutes later my nose had begun to burn, the roof of my mouth felt as if it was raw and my head was throbbing. It lasted for longer than 2 hours but about a hour after the pain began it started to hurt less. The pain got worse and worse every few minutes. Would not recommend this product to anyone!
