Re: Im hypothyroid and so tired
My advice would be to try alternating the two doses now, then retest in 4 weeks to see whether your free T4 level has improved over its starting point. Hopefully, your FT4 was tested, and the doctor isn't just looking at your TSH.
Three days is a very short time to feel effects of that increase. T4 builds very slowly in the bloodstream, so it would be unusual to feel hyper after just 3 days.
I know it's hard, but you really have to be a patient patient when it comes to thyroid matters.
