Over the last couple of months I have tried T4 75 mcg and it made me more hypothyroid although my FT4 and TSH levels seemed fine, but my FT3 level was not even mid-range.
I then added some 12.5 mcg T3 and lowered T4 from 75 to 25 mcg upon endo's recommendation. On this I felt the worst I have ever felt in my life!
I then dropped T4 completely and in the matter of 7 weeks upped to 85-90 mcg T3. I had a mixture of my old hypo symptoms and a fast heart rate.
Then accidentally one evening I took another 30 mcg of T3 and from the next day onwards I was able to lower my dose to 30-35 mcg T3 per day. I was little hypo, however my resting heart rate was always in the 90s and I started getting hot flashes and sweating.
I lowered T3 to 15 mcg daily and got back on my initial dose of T4 - 75 mcg.
Then in the matter of 7 days I dropped T3 completely and went up to 100 mcg T4.
I felt fantastic on this dose, realized I had forgotten what it was like to feel normal again. My energy levels were superb, I would sense only 2-3 flutters a day (my main hypo symptom - thousands of ectopic heart beats all day long).
My blissful moment was shortlived however. It lasted me only for a week after which I began to get more and more hypo.
A week later I upped my dose to 125 mcg T4 and again - I was feeling fine for a week and then started getting hypo again: many skipped beats, achy all over, and falling asleep 3-4 times during the day, absolutely no energy.
Tried adding some 5 mcg T3 on top of 125 T4 - very bad decision, felt even worse.
Now I dropped the T3 and intend on upping T4.
Apparently, at least from what I've read, T4 doses that are too low to shut the thyroid completely down only downregulate its function and the person ends up being even more hypo than before starting T4. Adding T3 produces the same effect, alas...
I want to try some NDT however I want to give T4 a chance first but I am afraid that I won't reach a dose that will heal me.
My FT3 is mid-range now, and I feel best with an FT3 on top of the range.
I am beginning to think that there is no chance for me to ever get better and I will be hypo in the next 5-10 years and then die of hypothyroidism affecting my organs and systems.
I have Hashimoto's, no TT, went gluten-free a week ago.
Is it true that 200-400 mcg T4 doses were prescribed in the past?
If so, why almost nobody tries it nowadays?
P.S. I am now convinced that I process even T4 very quickly. When I start/stop taking it, I can tell the difference right away, don't have to wait for 7-10 days.
