Thanks for sharing your story. How are your adrenals and thyroid? Having done everything naturopathic I could for my hormonal system I've been learning in the last year how closely it's linked to my liver which in turn was troubled with flukes. So it may be that if you improve your liver function your thyroid will strengthen and your metabolic rate increase? You can test your thyroid and adrenals at home, thyroid through taking your temperature and adrenals through a blood pressure test: take a resting pressure sitting or lying down and immediately stand up. Take it again. If the top number falls it's a sign of adrenal fatigue.
Incidentally, adrenals do not like too much exercise, which can overstress them.
I was talking with a practitioner today who specialises in parasites. He says that we can never be sure to have got them all. The strategy he recommends is to use a parasite cleanse and mop up programme together with Liver Flushes to get the situation under control and then do everything possible to strengthen your digestion and immune system so that no creatures would want to live in your body.
