Sorry to ask even more questions about converting T4 to T3?. I think I may not be converting properly as I feel more unwell after being diagnosed, and taking 125mg Levothyroxine. Since taking Levo I now realise how well I was before diagnosis!. My question! We are told to take our medication without fail, otherwise we could become very ill, even be life threatening! BUT! If we are not converting our daily Levothyroxine T4 to T3 is the medication having zero effect on our thyroid problem, because,if it is not achieving what it is supposed to? Is it a waste of time, could I take a Cadburys chocolate button instead? far more enjoyable in my opinion, and probably as useless for my thyroid problem as Levothyroxine!!?
