Hello. I've been on T3 only for a couple of years but with mixed results. I was very unwell at the start of this year and my new GP has prescribed armour thyroid. She is starting me off very slowly on 1/4 of a grain, gradually increasing to a half and I still take some T3 during the changeover. However, I have tried on a couple of occasions to increase the armour from 1/4 to 1/2 grain and find I get a new and weird tiredness. It is not the awful toxic tiredness I got on T4, almost like a feeling of gentle sedation spreading through every cell in my body. It doesn't make me feel ill or agitated, just hugely tired in a genial kind of way. Really odd.
Last time this happened I went back to 1/4 grain and the feeling went. I have tried again increasing to 1/2 this week and the feeling is back. I just want to sleep and am back to thinking it is time for bed at 7.30/8pm after having slept in the afternoon and having not done much during the day and having to push through to do what little I did.
Both T4 and T3 made me feel like I was being poisoned when I first took them. Is this tiredness with the armour something I just have to put up with initially? I guess in terms of side-effects it is an improvement, because although it is limiting, it is not making me feel ill.
T3 often made me feel agitated and I feel much calmer on armour so I would like it to work. I am quite bewildered by this reaction as my gut instinct has been that armour is right for me.
Has anyone else had an experience like this with armour?
Thanks
Dee
