Testament to there efficacy. I've had insomnia for years, can't sleep through the night. I've tried huge doses of everything on the market, from Lunesta, Ambien and Lorazepam to Unisom and Benadryl, melatonin, valerian, passion fruit extracts...etc...added CBD D9 to the mix and finally able to fall asleep. I wake up at 2am every night, I don't even need a clock anymore. So the stupid USPS in Atlanta has opened a new distribution center that has delayed mail for weeks, my shipment from Klova was delayed more than a week and I was without. I was up every night. I finally got my patches yesterday and I stuck one on last night and slept through the night. I will always have a subscription to these.
