I have been on Synthroid since about 1995. I had a thyroidectomy and do not have a thyroid anymore. I have been on 0.175 mcg for about 10 years and did not have any side effects except for fatigue and a little depression.Everything else was pretty good. My TSH is registering low so my doctor moved me to 0.1 mcg of Synthroid and 5 micrograms of Cytomel. I took this for about three weeks and for the last 1.5 weeks have had awful headaches and the dryest eyes ever. Something, I have not experienced before. My doctor keeps saying he wants to help me but does not listen to any of my symptoms. I actually pulled off the symptoms from the list online of hypothyroidism and have 15 out of about 20. I am wondering why I felt so much better on the higher dose than this low dose. Can anyone releate. I am starting to think maybe my body is not processing this right. The funny thing is is that my lab work came back with normal results today, which means my doc is probably going to keep me where I am and I feel the worst I have felt in ten years.
