Boy does that sound familiar!!! I developed a new empathy for children with Attention Deficit Disorder while on PTU. I kept a zillion lists (forgetting where I put them), measured my four-times-daily PTU doses out in little vials, so that I could tell whether I’d taken them or not, and kept apologizing to the world for forgetting things. It cleared up within days of me going off it in preparation for RAI. I never thought “hyper” would be better than something, but I can tell you, I’ve definitely been happier with this month of hyper than I was wandering through the fog.
