To Jess3648- I really can't comment to much about valerian. I was taking Calm Legs for my RLS and it was in the tablet. I also have sleep apnea and didn't want to take to much of it cause I didn't know what kind of reaction I was going to have to it. I didn't use anymore than a quarter to half a tablet and it knocked me out good. The doctor said it wouldn't harm me. Ask your doctor first or try calcium/magnesium it helps relax you so you can sleep better.
