Hi Everyone, I have been on T3 for 10yrs + due to Hashimoto's. My thyroid is now failing more and the GP has added 25mgs 3x a day of T4. I feel low mood, anxious for no reason and fed up as hoped I would start losing weight. Has anyone else been able to be treated with T3 only. I get the impression it is more expensive and the GP would prefer me to be on T4 only. I have struggled for 10yrs to keep the T3.
