Thyroid hormone conversions

I used to take Levothyroxine and was on 100mcg a day, but felt pants on it so approx 5 mths ago I swapped to NDT. I did have a few downs and ups but am on 2 1/2 grains at the mo. It's still very much early days for me, but I still don't know if NDT is the right course for me and I like the idea of the Levo/T3 route purely as you can alter the doses separately. Any change won't be for 4 - 6 weeks, as I'm just getting over a hyper stage and through some sensible advice from Clutter (thank you :D) I'm getting my dose sorted finally ;)

My question is If I decide to revert back to Levo and opt for T3 to go with it, what starter dose would I need, and what end dose should I aim for? And how often and in what size dose would I increase? Also would I simply go straight back onto 100mcg Levo or would it be sensible to start on a lower dose and build up. Although I don't really want to have to start over, on a low dose of Levo really as the thought of getting all my hypo symptoms back is not something I want :/

I've been hypo 15 years, but recently been diagnosed Hashi's through a private blood test ... glad I did that one lol

Jan, I've just PMd you. 2.5 grains is equivalent to 100mcg T4 and 20mcg T3 in round numbers. There's no need to titrate dose, you can switch straight over.
