After saying enough is enough with twitches, leg and foot cramps, anxiety, and sleepless nights full of worry and dread, I went to an acupuncturist. After about 3 sessions, my cramps have greatly decreased, and I twitch only a few times a day, vs. a few times per hour a few weeks ago. In short, my BFS symptoms have improved. He gave me these pills called Tian Ma Gou Teng Wan, please do a google search to see what it is about. In short, something to do with calming the liver. He also gave me some red pills to try, I don't know their name, just a long list of ingredients. However, they seem to calm me down quite well. Its worth a try! Of course don't try and buy anything over the internet, even if it is for sale online, you should still see a good acupuncturist who will provide you with the herbs.
God Bless.
