I have been taking earths secret magnesium and sleep for a month now. I have started to feel more calm in my body and mind. My twitching legs have eased. I can drift off to sleep better as my mind is not racing as much…

“No side effects at all for the following day”
This is the best tablets for a decent night sleep for me. I have tried quite a few. Earth’s Secret does not give me any side effects at all for the following day and I definitely sleep better after taking these tablets.
