I Have Been Experiencing All The Symptoms Of Thyroid Problems

I have been experiencing all the symptoms of thyroid problems for quite some time. I had a ct scan less than a year ago that shows what was 1 nodule to several now. two of the cysts are 4x5 cm, others are 3 and 2cm. I was started on thyroid meds but my dr keep reducing my prescription because I don't fall within the correct lines on the chart. I feel awful all the time. What can I do
