Makes me a bit sleepy/tired

Posted by Reviewer2158986 on Sep 18, 2014

I took this before bed a couple of times, and couldn't get to sleep for hours, even though it makes me feel tired. There is a relaxing feeling that comes over my body after taking this tablet (not a placebo effect). I'm trying the natural factors brand tomorrow because it's sunflower and the inositol content appears to be lower. I suspect (and hope) it's the inositol content in this is whats making me feel tired. I've noticed I'm very sensitive to medications and natural supplements.
