One more thing to add to Travler's suggestions…
If you are experiencing sugar cravings, you have a yeast/fungal overgrowth. Sugar cravings are not a natural state of the body. Also, y/f overgrowth causes many of the same sx as lyme & co… so cravings are a sure bet when otherwise, it's hard to tell if you have y/f overgrowth with all the sx confusion.
Cravings like this are part of the neurotoxins created by the yeast. It literally changes your body chemistry, it is the yeast tricking your brain into wanting sugar, which it depends on, not you. So, if you find that you're tired of fighting it, a local anti fungal will end cravings immediately. And you'll have a little die off, which can make you feel awful for a couple days… then the sun will come out.
