I have the same question as April, what meds are you taking. The answer to your question is yes, I have often thought my synthroid tasted sweet, as if it had a candy coating. Never questioned the Dr. about it though. I guess I didn't think anything of it as long as my blood work showed improvement.
I went to a group of Drs for over 4 years who thought TSH was the holy standard of thyroid measurement. I have found a Dr. who does things differently now. If your Dr. refuses to do a free T4 and free T3 perhaps you might want to look into changing Dr.s if you ins. allows.
Best of luck to you. May God Bless and Keep You
