Hi David,
while I am not a Grave’s patient, I am married to a man who was diagnosed with Graves a year ago. This rage sounds exactly what my husband goes though, including the crying and fatigue. It is very frustrating to watch him go through this “rage”. It is as though the smallest thing can set him off and nothing can stop it, He has to go through the whole thing until he cries and then sleeps it off. He is always very sorry but it is till tough to go through. There doesn’t seem to be any help other than the pills and waiting for him to stabilize.
Good luck to you,
DG
