hi, all. still trying to figure out my optimal NDT dose after months (years). labs look like this:
(after previous raises and lowerings and moving from NDT + T3 + T4 to just NDT):
i was on 2.5 grains NDT (raised from 2.25) for six weeks, and labs 16 october were:
Free t4 1.66 (0.82-1.77)
Free T3 4.7 (2.0-4.4)
i had some palpitations at this dose and so given the heart issues and the high result, i dropped to 2.25 grains again. decided to test after 3.5 weeks (although i know that's not really enough time--but one of my good doctors mentioned that it's okay to test after 2 weeks, even if not ideal).
results 19 november, after 3.5 weeks on 2.25, down from 2.5 grains =
Free T4 1.65 (0.82-1.77)
Free T3 4.5 (2.0-4.4)
the lab was the same and i fasted and had the blood draw first thing in the morning both times, so testing conditions were the same. i had also not taken any thyroid med for 18-24 hours prior to the test.
previously, in the summer, i had a much lower lab result on the same 2.25 grain dose, but that was in a different country / with a different lab. (but still with fasting and doing the labs in the early morning and having 18-24 hours without meds before the test). i'm really having trouble understanding. on 2.25 in august, i had the following result:
Free t4 15.3 (10.0-28.0)
Free T3 6.2 (3.0-9.5)
maybe there's no point in looking at the august results, maybe the hashi's has been making my thyroid spit out different amounts at different times, maybe the variation in labs makes a difference....? i'm just really confused. why would 2.25 be a middle dose at one point and a high dose at another? leftover high levels of t4 in the system still from previous dosing months ago? more importantly, what do i do now? the 2.25 dose is definitely better for me than the 2.5 was, in terms of heart pounding, but i'm still tired often (and wasn't at 2.5) and my sleep at night is the pits now. i wake up after 4 or 5 hours. i thought i might need to go up again. instead, i can't tell if i need to go down. really, i'm thinking that i should just stay at this dose for a while longer and see how it goes, but it's very confusing. any enlightening details appreciated!
