I'm going through the same thing and have recently found relief. I would get severe bloating after eating. I also experienced fatigue.
Through desperation on the weekend I did a lugol's enema and followed it up the next morning with a kefir enema. I had fasted the day previous. I expelled LOTS of candida, mucous, and a few worms after the kefir enema. I also just started making wormwood tea, and pau d'arco tea which taste awful but works wonders for me. I bought the dried leaves, and bark and have been having it twice a day. I wasn't diagnosed with Candida, and my stool samples came back as negative for parasites or ova although I've seen them in my stool.
The pictures below are a small fraction of what have come out:
The first is a worm from the lugol's/kefir enema combo after a day of fasting and the second is from a liver flush a while back. Anyway, to summarize: Try the lugol's enema followed by the kefir enema and give gluten-free a test (unless you're positive you don't have an intolerance). Do the tea as well and as awful and bitter as it is, it will definitely help with your symptoms if they are candida/parasite related as mine were. I also just got back from the doc's lab and they're checking my blood for a gluten intolerance (celiac).
Believe it or not, despite being a superb energizer, wormwood is one of the bitterest herbs that are used by herbalists across the globe. The herb has several medicinal qualities and that includes increasing hunger (appetite), augmenting digestion by enhancing the secretion of digestive enzymes as well as bile from the liver and gall bladder and inciting peristalsis (wavelike movement of intestinal muscles that propels food along the digestive tract). As the plantís name suggest, wormwood can also be used to throw out worms from the body and it is also a superb medication for anyone suffering from weak, lethargic digestion, contaminants as well as jamming in the gut. It is also beneficial in solving liver disorders in people suffering from a sensation of being run down and incapacitation during convalescence. The presence of chamazulene (an anti-inflammatory agent) in the unstable oil obtained from woodworm extracts has a soothing effect on the digestive tract.
