After my latest set of blood results GP and myself agreed 50mg thyroxine was best for next 8 weeks when I would have more blood tests. GP did want to put me on 100mg but i think my system didn't absorb it all if that makes sense, and went hyper. Would rather build up slower this time. She does think I may have also hashimoto antibodies as well as Graves, and will test and refer back to endo, but wants to see what next blood test results are. I rarely feel good, but feel slightly better when underactive than hyper. Permanantly feeling hungry to the point of low blood sugar nausea, faint and shaky is not fun, especially when at work, or out and about you cant just have something to eat. Eating is difficult because of so many sensitivites, and digestive problems, so this is one of many reasons why if not stable i would rather be under.
