FT3 - Is it really all about raising this? (levothyroxine)

Just discovered this forum!

Diagnosed a while ago, maybe a year now, still finding the right dose on levothyroxine.

On other forums I noticed they are all about increasing levothyroxine to get FT4 higher in range, like 70% or more, and FT3 a bit behind it with no attention paid to TSH even when it’s non existent on levothyroxine.

In some ways, I feel worse on lower TSH (been overmedicated too… awful and still hypo symptoms anyway) with a FT4 over 70% of range, and slightly behind FT3. Just a different kind of worse.

It’s been suggested I add T3. I am worried about the suggestions on that forum, so thought I’d try here.

So, I just want to ask do people feel better with low FT3 on just levothyroxine? Is that possible? Or is all about getting the FT3 past or at a certain point?

FYI I am not slating other forums, just sharing my experience.

Currently on 88mcg as over medicated again, been on 100mcg twice but overmedicated. Doses below 88mcg seem too. Last blood test, TSH non existent, FT4 slightly over range, FT3 around 70% through range.

Really would love to read others experiences!
