Hi John,
I’d guess the exhaustion is not related to TED. Unless the ongoing two year plus stress of vision has pretty much drained your gas tank.
I don’t recall your Graves’ status. Are you on a thyroid supplement now?
I guess the first thing I would do is have my thyroid lab panel checked, then when you have that, plus maybe having hemoglobin and hematocrit, check with a doc, see if any med can be tweaked.
How long has the fatigue been going one? The other reason is that the anesthesia from having the OD, plus the recovery, pretty saps people for a few weeks. You are only two weeks out from that, too.
