I have recently been diagnosed with underactive thyroid & am now on 75mg of Levothyroxine after asking the doc to up it as my symptoms were not improving despite 'normal' blood results. However I'm finding it really difficult to get a decent nights sleep even with prescribed sleeping tablets. I've even resorted to sleeping in the spare bed to try & help but it hasn't is there anyone else who also has this trouble? From some of the other blogs Im wondering if I should ask to change the medication? Any help would be much appreciated!!!
