hi @ KGEB, i am currently on this regime, just had my 2nd cycle but i also have mets and this is now my 10th line of treatment,and like you have hashimotoi, although since my diagnosis my endocrinologist has kept a eye on my levels and every time i start a new treatment i have my levels tested as he explained to me, he just did not know what these drugs would do to me, i am currently on thyroxine and tertroxin, so perhaps a thyroid function test would be an option.
The fatigue is bad and i really do understand what you are saying, i also have the eye problem as well,this is something i have learned to live with over the years,do mention these effects to your oncologist as we are all different and react to these drugs each in our own way,if you have just had your last treatment, please do be kind to yourself, your body and mind have been through an awful lot lately and now needs time to adjust,if you need to rest, rest,if you need to go to bed, go to bed, its okay!!!, allow family and friends to help out, you are not superwomen,do what feels right for you, allow your body to do its job.Its a hard path that we all tread on this breast cancer "journey" and we all do it in our own way, please get your thyroid levels checked as you may need an increase or decrease in your medication.
take care,
