I have switched to Thiroyd after over 20 years on levo-only meds. For anyone who saw my post last week about blood sugar issues, they seem to have resolved themselves, which is great, and I am definitely sleeping better. Still fighting the seasonal allergies but hopefully that will end in a few weeks. I have sort of a theoretical question, though.
I know the standard advice is to GO SLOW with dose increases. I am wondering if the whole "dry sponge" analogy applies even when you have been on t4 for years. I am holding right now at 1.5 grains taken all at once in the morning an hour before eating and will hold there for another week before assessing if I need to make any more changes. I definitely feel better than I did last week on 1 grain only. I definitely don't want to overshoot and imagine that 1.5 grains will probably be the correct dosage for me, but it's more out of curiosity - if you've been on t4 for years wouldn't the figurative "sponge" already be "saturated"? The waiting for conversion issue shouldn't be an issue, because you've already got t4 converting (or not converting, as the case may be, ha!) in your system. Is it just the t3 that will cause this "dry sponge" effect?
Thanks to all you science nerds out there!
