the dark circles are indicative of kidney problems. keep track of urination volume.
not sweating is an adrenal issue, you probably have low aldosterone, recommend consuming more salt.
licorice can help the adrenal issues but too much will either suppress them or act as a cholagogue (bile stimulant).

iodine will detoxify the body of halides but it can also overstimulate the thyroid gland which will in turn cause stress to the adrenals, which are already weak.
the weight lifting fluid retention can be attributed to weak adrenals/kidneys. salt can take care of some of this problem and the correct dose of licorice. i suggest not lifting weights and doing less stressful exercise like light walking/jogging/tai chi.

the 'intestinal support' supplements you take are specifically parasite herbs. you definitely have parasites. this could account for the whole problem, or only part of it. suggest greatly increasing the dose of your parasite herbs to tolerance and adding in anti- parasite foods: coconut, pineapple, papaya seeds, pumpkin seeds, salt water flush, apple cider vinegar, turmeric, vidanga, cayenne, garlic, raw onion, perhaps allopathic worm meds.
