Up to 200mg levothyroxine feeling crappy

[Maryanne2173]

Hi my name is maryanne I have been diagnosed with an underactive thyroid for about 6 years now. It stabilised for around 3 years on 150mg of levothyroxine but then this last year I was increased to 150mg and now 200mg which im told is a high dose. Since being on the 200mg I have noticed im getting bad headaches which are making me feel sick and am on the toilet all the time I also seem to be gaining weight again.

FT3

Thyroid antibodies (TPO and TG)
