I have terrible sleep issues that may be related to fibromyalgia. I just read an article on fibro and it seems to be the only thing that carries a possible genetic link. My mom (86), me/male (59), and my youngest son (12) all have major league sleep issues. It skipped my oldest son (16). The article, "Losing Sleep over Fibromyalgia" at www.lifescript.com pointed out the possible genetic link and the sleep-related issues. Sleep issues are more apparent than pain issues typically noted with FBM. Also, just read here that L-Tryptophan may interfere with FBM. Any thoughts?
