My insomnia is now chronic, but before I slope off to my GP who will prolly put me on pills I'd prefer to try something more natural first. I've heard good things about Valerian. Has anyone any experience of it, and if so what dosage? I saw some tablets (90 mg) in H+B which stated '1-3 tabs per day'. Is that in one go or spaced throughout the day? No more info on the bottle. TIA.
