so I think I have a plan - I stopped taking the 25mcg of T4 last week as I was concerned about my fast heart rate - more so than my doc who said stay on it - its not his heart after alll!!! I'm feeling slightly better (please god don't strike me down) - now not sure whether its was the 2 months on T4 or the TD b vits I've been using at the same time. I got a TSH result back 4 weeks ago down to .66 from 2.?? T4 was out of range <22 mine was 23.5 - I was taking 50mcg of T4 at that time and was feeling very ill with vival symptoms - vertigo etc. soooo - given my high cortisol levels I was looking at the Dr W adrenal support plus a crumb of the naturethroid at the same time to start with. What do you think?
