Discussions that mention prozac

Thyroid Disorders board

I had my thyroid zapped with RAI in about 1976. Since, I have had bouts of depression and was put on Prozac in 1992. This October my doctor reduced my Synthroid from 175mcg to 150mcg due to a TSH of .08. About mid December my depression has come back.
After finding this site, I would like to get my thyroid to an optimal level to see if it would help my depression. My doctor is pretty clueless on testing so I thought I would get tested through Health Check USA. I know I need free TSH, free t4 and t3 tested, but do I need to get any antibodies checked even if my thyroid has been zapped?
Any other testing or advice suggested?
Thanks in advance.
