chicken or the egg or both? Have had undiagnosed and untreated lyme for a while -- used to joke that I would never do a low-carb diet -- all I craved my whole life was breads and chocolate -- now they are nonos -- was that my Lyme or did my yeast overgrowth cause problems? I know for sure I had a bullseye rash 7 years ago and test positive for western blots then and now but I had other "lyme like" symptoms since age 5
