The formula was designed with Jacob Teitelbaum. The contents are: Valerian root extract Passionflower Leaf and Flower Extract L-Theanine Hops Flower Extract Wild Lettuce Leaf Extract Jamaica Dogwood Root Extract Wild Lettuce Leaf They come in "ultracaps" which just look like gelatin capsules to me. I bought them at the health food store. I plan to take one tonight. I've been taking Ambien for years, but would like to stop. No weird side effects, just want to try something more natural. I tried 5-HTP and it didn't help. Just gave me a bad headache. Has anyone had any experience with the Revitalizing Sleep Formula? I'd like to hear the good, the bad and the ugly stories. Thanks!
