 However, I will tell you this. If I weren't, I would definitely try Z-Factor because I know how good Relief Factor is. And if they come out with a product to help you sleep, I would try it. Especially if you are now taking a prescription medication to help you sleep. It's always better to have a non-drug than a drug. You should take the drug if that's the only way you'll sleep. I'm not a fanatic on this.
