PTU is just the other alternative to RAI. It stands for Propylthiourac, which is a medication to control the thyroid hormone levels. I am not on medication any longer since my Graves is in remission at present. This remission might not last and I will have to have RAI treatment.
I am feeling better now, but still have a lot of fatique just like you. I keep thinking that it might just be old age catching up on me.
I hope you will keep your chin up and have a Happy New Year! Thanks for writing me. Will hear from you soon.
