I think that's just an indicator of how the body absorbs and responds to the medicine. Not Hashi's in particular.
Thank you to you two for responding! Is that an indicator of hashimoto's to feel as you said "When I raised dose I would often feel better for several days to a week or so, and then crash again" or just hypothyroidism? That's how I've been feeling and it's getting old. :(
It takes the T4 portion at least 4-6 weeks to reach full potential in your blood; the T3 would kick in much sooner than that, but 5 days isn't very long AND temperature is not the only indication that a thyroid medication is working.
No, I don't believe that's an indication that your body isn't accepting the Armour.
In my experience, I can feel an increase in desiccated thyroid meds within 2-3 days. It's true that the T4 component will take longer to kick in, but since desiccated is mostly comprised of T3, I would expect you would feel *something* after 5 days. If not, it may just be too small of a dose still. When I raised dose I would often feel better for several days to a week or so, and then crash again, which would prompt me to raise again (this was up until 2 grains, at which point I slowed down the frequency of increases). Everyone is a bit different, but if you are still freezing and dead tired, I would hazard a guess that waiting 4 weeks for the T4 to kick in won't do you too much good. But if you need to wait that long to consult with your doctor about a dose change, then that may be what you need to do. Hang in there.
