TSH definitely lags ~ I’ve heard up to six weeks can pass after changing a dose before TSH really reads *true* ~ but there’s also the fact that switching doses can trigger a period where we feel up/down for a little while. It sounds like your doctor is doing the right thing ~ I would continue on that path until six weeks have gone by, then see what the lab results are, and proceed accordingly. It’s part of the particular torture of thyroid disease, all this waiting while we feel SO CERTAIN we know what to do immediately, but it’s necessary to make sure we aren’t always chasing a moving target. We have to be at one dose long enough for the body to fully metabolize our reaction to it, test, then change to accommodate. You can at least know for a certain fact that you will not spiral into the hyperthyroid heights you attained while sick. And for now, take it easy.
