Yea know that feelin well!! mine seemed fine for ages but having to change dosages again as i feel like shit/tired all the time at mo.

If its overactive like mine was you can eat as much as u like and be thin as fuck but some of the side effects aint nice!! I looked like a heroin addict i was so thin!!

If its underactive then you put on loads of weight etc, unfortunatly the meds dont work with everyone and is an life long struggle with it! Could be alot worse thou so
