underactive thyroid
"I really hope this helps someone, I've had a underactive thyroid for 5  years, it has been very difficult but I will say this thyroxine does help but it must be taken regularly, also I was prescribed vit b12, vit d, iron, I was also diagnosed with sleep aponea.  So what I would suggest anyone with under or over active thyroid should get the things I've just mentioned checked just in case. If the doctors had done it sooner it would've made a dramatic change to my health as I'm told its quite common if you have a under or over active thyroid. It's your life doctors won't bother going the extra mile. Good health to all."
