I've Been Taking A Medicine For Hyperthyroidism And For The

I've been taking a medicine for hyperthyroidism and for the past eight months I have been suffering from the problem of not being able to relax or rest well. My doctor thought It might be caused from restless leg syndrome and gave me treatment for that but it hasn't helped the problem of my restlessness and anxiousness that I'm feeling. Is there anything I can do to help this?
