Hi was on 100mg for 24yrs then seen a private gp last year he said I'm a touch over drop it to 75mg Now today I have after 1 year of misery going back to 100mg Levothyroxine as my testosterone levels have dropped too much especially my SHBG Endo reckons going 25mg higher could indeed help me. Now I can't have Teva brand But can Have mercury pharma Eltoxin & accord. Endo told me my TSH what ever that is is too low. What dose can I expect to land at? Since March I've been diagnosed with secondary addison's disease my pituitary glad has stopped working No Testosterone No Cortisol No thyroxine. I'm very worried as I have daily headaches which are bad from 6pm onwards my sleep I wake every hour & wale up feeling terrible. Any pointers here I can do? Itsxmy first time on this sub. Thanks
