Hello Princess,
I just wanted to let you know that my father also developed hypo thyroid while on sutent and he also takes the same medication to treat it. Has worked for him he had to adjust the dose a few times, however the thyroid function test are now in check.
As for the sleeping issue, maybe instead of a sleeping aid. Maybe try anti-depressant. My father also takes one of those. He seems to be more relaxed now. Does your hubby take naps? Maybe its to many. Please let us know how things are.
Thinking about you and all the warriors on this site.
A Friend Wendy
