I do not normally leave reviews, but let me tell all you arthritus sufferers, there is help out there. For 25 years I have suffered with knee pain. I have been prescribed by the doctors over the years so many different painkillers, I became addicted at one stage and had to ditch them. Since then, everyday is literally an uphill struggle. I had to bath in the morning, just to be able to function for a few hours. I read the reviews, but I am a born cynic and I struggle to trust people/reviews, believing they are all made up to line the pockets of the seller. I started putting these drops under my tongue as directed, morning and night. Day 3, I woke and stepped out of bed and I swear to you, nearly burst into tears. No pain.... I did not want to get carried away, thinking this is maybe a placebo effect. I have to share this guys, it was not. My job, after work is very physical and demanding, increasing the discomfort..... let me tell you, not any more. I can squat now (not done that in 25 years) I'm sleeping better as I'm not being woken by the pain anymore. And I'm only on day 10! This is no joke, no wind up or sales patter, I get nothing from this apart from sharing just how wonderful I feel everyday now. Thanks GB,
