My husband started using the O-spray as soon as I handed it to him, two hours later his fever went away I could not believe it, but thankful at the same time. Tonight has been his first fever free night in 9 days and he also was ready to eat once the fever went down. I want to thank you so so much for taking the time to tell me about the spray, I had been so scared for the past week I thought I was going to lose the love of my life.
