After taking a flouroquinalone drug, and having a bad reaction, my sleep has suffered terribly. I was in an almost state of panic all the time. I'd start to sleep, and suddenly pop awake. Magnesium glycenate helped, but then I started taking the advanced memory formula, and I have seen a dramatic improvement to my sleep, and my ability to handle stress during the day. I highly recommend it to everyone, because these days are stressful for all of us.
