Sorry for the reason you're here but, glad you found us.
Pat yourself on the back for working towards getting a proper diagnosis and treatment.
The meds titration process is quite individual-specific. Many people are able to optimize their levels/doses within six months although the average does seem closer to a year.
It took 15 months for my levels to finally optimize and stay that way. I hit my optimal levels twice during the meds titration process so, didn't always have steady dose increases. And, I need my levels higher than most for me to be symptom-free. These two types of situations add time to the process.
I think the best anyone can do is to get labs every 6 wks. and push the doctor for dose increases until levels are similar to the types of levels healthy people have: FreeT4 and FreeT3 around 60-80% of range.
Based upon your lab's ranges, this would mean FreeT4 1.4-1.6 and FreeT3 3.4-3.8
Then, if symptoms remain, ask the doctor to tweak the dose in the hopes of eliminating them.
I don't know how to interpret adrenal labs but can tell you that rhodiola rosea has been shown to help with stress and improve adrenal function.
Best of luck to you moving forward!
