Hello - I've not taken Cytomel (and am not a doc), but based on the prescribing info, it looks like the concern with older patients is with *overtreatment*.
You mentioned that you had weaned off over several weeks - maybe now you can sit down with your doctor and go over new labs - perhaps taking a look at Free T4 and T3 in addition to TSH to see where they are?
The fact that you had no issues just a few weeks ago, but are having symptoms now, is something that your doctor should take seriously!
