definitely sounds all a bit too much. night time sweats i get when i eat gluten so generally associate them with a bad allergy to something. nails are nourished by the liver in chinese medicine so weak nails can for sure be from overburdening the liver. i can't take supplements anymore. i don't think i would if i could. what works for folk in acute conditions cannot necesarily be extrapolated to chronic conditions, especially where digestion and the body's ability to process, and thus make use of said supplements, is gonna be greatly reduced...and whats not correctly processed, itself, becomes another cause of toxicity. its a good reason to go for energy medicines like acupuncture (electroacupuncture at home, not needles), complex homeopathy (multiple remedies at multiple potencies that remove practitioner skill and is better suited to chronic health conditions) and my personal favourite, which is polairty therapy using "pulsors"...physiological relaxation = die off...there's no better way ime.. introducing no physical substance to the body and only removing what is burdensome...hopefully. ..and the diet has to be right to support it. i no longer see any practitioners but was never told buy them that they would definitely cure me...though i think a couple thought they could...and everything in its right place, they/it might have done. chi transference from a tai chi master was really something...but then i got home and did my own therapy with and boom, too much. like someone else said, even the me/cfs docs have little clue and are really crossing their fingers that it all works. money back guarantee? why not...i think they all should. tricky if what they're presrcibing is very reliant on you eating a s[pecific diet etc and whether you do that with a treatment. i don't think herbs and supplememnts can help much here. i did hear of one lady in a local newspaper who claimed recovery on herbs though i think she was within the first 3 years when i think such approaches may still be viable...and of course then they think its viable for everyone!
