So i upped my thyroxine to 150mg one day then 175mg the next. My prescribed dosage is 150mg a day. I have felt great full of energy although i struggle to sleep a little. My dr rang today as i had requested some 25mg tabs and he told me not to increase them as this will cause more damage. Mentioned ostioparosis (spelling isnt my strong point). Being an anxiety sufferer i now dont know what to do for the best. He said they will test again at end of month. Im at my wits end with it!
