|yes i have had all these symptoms & lots more.Some of you say it's relative to thyroid, correct.we are ( i was) so hot at night, & i also had symptoms of MS which my sister has been diagnosed also. It's true, it is thyroid related & i found alot about it by googling ithyroid.com, natural salt, & water in water out. I don't overheat, actually this summer i slept every night with a blanket on. I don't get the muscle cramps & spasms, I have lost weight & my blood pressure has reduced from 150/80 to 122/64. It's all about balancing the nutrients in our bodies.
