Now Ive been on my thyroid treatment for over a year now and my levels are with in range.For the past month I have been really tired again and sleeping 12 hours a day,,my weight over the year has dropped over 50 pounds, I went from 245 to 195 and Im 6' 4" male this is not good for me.No other test show any other problems. I feel im at to high a dose and my levels should be above normal..This is getting worse. I'm eating well but my vitamin D is still low and with my kidney stone problems still, and I cant seem to handle the water pills any more since I work here in the desert, The sunlight is not recommended by the doctor during the treatment on this med..Im in a area were doctors and good hospitals are short and not very good. Maybe a multi vitamin of sorts is at hand here. I still have anxiety problems twice a day with tingling in legs and arms,,My vit B12 is good I take injections every month, And I take zanex every day just half tab of .5mcg twice to make .5 total for the day.
