Finally managed to write my emails as suggested by my endocrinologist, mainly to my MP, Health Secretary & Chair of the East Lancashire NHS Trust to ask why I'm unable to do a trail on liothyronine to see if it will help me etc. I've also asked my endocrinologist if he can provide a prescription via the private route, so fingers crossed something good will happen but I won't hold my breath.It's a postcode lottery there are a few other NHS trust that do not supply liothyronine due to cost mainly.
I'll come back with any information I get.
Otherwise I'm managing reasonably well so far thanks to taking betaine HCL which helps my stomach hopefully helps absorb the loads of vitamins I take.
