Underactive Thyroid
"I was on levo first for about 3 months. Blood test came back with good numbers. Only I still felt like crap. Doc changed me to nature throid . I felt sooooo much better.  I needed the T3   ( levo was not converting the T4 ) I take 195 mg a day. 2 pills in morning. 1 mid day ... My insurance does not cover. But $40 gets me a 3 month supply"
