I really don't know where to turn with this bloody disease anymore! Been on thyroxine (125mg) for 2 years and feel like absolute death most of the time. The latest thing is grinding my teeth at night and waking up in awful pain with them, anyone else had this? I really am wondering if the medication does more harm than good?? I am 36 and feel like I am 86, everything is hard, just want to sleep all the time! Need some advice!
