I started a combo of T4 (50mcg) and T3 (20mcg split into two 10mcg doses) a few days ago on prescription as I wasn't getting on with just T4, I was on 100mcg.
I've not felt great, feel a bit hit by a bus and quite nauseous. I'm taking my first dose around 6am with the levo then the second around 1pm on an empty stomach.
Is this a high dose? Should I have started lower?

If you were already taking T4/T3 it's not a high dose. You have to give it time for your body to settle and I'd wait at least six weeks. Your combined dose is about 90mcg of levo.
Also if you take your 1 p.m. dose your stomach has to be empty before, and after. If you've eaten a meal about noon you might have to leave about 2.5 hours before taking T3. Our digestion is also slow.
T3 is the only active thyroid hormone, T4 is inactive and it's job is to convert to T3. Maybe it doesn't always if people have problems with T4. This is from an expert who himself took 150mcg of T3 daily as he was thyroid hormone resistant. His recommendation was once daily dosing. I think it's easier to reach an optimum as your body reacts to too much and you reduce back:-
I thought T3 was three times stronger than T4 so if that is the case then msislissa would be taking equivalent of 110 mcg. levo. Or have I got it wrong.
You might find it better to spread your T3 doses out further? I take my first dose early am on waking, then a later dose either before my dinner in evening (around 4pm) or later just before bed.
