Constipation is one of the symptoms of hypo T. What helped me was magnesium (right type!) + vitamin B,C and iodine.
Having to pee all the time; may be mangnesium but also boron deficiency. This is where I have had most success in my cases with boron-magnesium + iodine.
Take the salt in any way you like; my kids cant take salty water as me; they prefer to lick on their finger, dip it in salt, then flush with water.
Taking my temp along the way showed the fact that I feel much better at 37+ C than 36+ C
