I'm interested in hearing any experiences regarding use of this product. My daughter has POTS and does not get restorative sleep. We have tried many things and are still looking for something that will help. She did find that magnesium provided a few nights of blissful, restful sleep, but it also weakened her leg muscules, so she unfortunately had to discontinue it. Thus far that is the only thing that has given her the restful sleep she so needs. Any feedback, positive or negative, is much appreciated.
