Just feeding back that my recent brand change of T3 to Thybon has made me sick with all my symptoms returning within 7 weeks. I managed to get docs to do another prescription and so back on Mercury Pharma again. Been on 6 days now and improving slowly again.
It's so bizarre when they say it's the same thing. I've never had a problem with swapping brands with levo as others report so a new one on me.
