I got my Thyroxin finally raised to 100mcg instead 50mcg, also got my eye appointment to hospital. Would be interesting to see if this 100mcg would actually help with my 'heat haze' eyes. Dr was very reluctant to get me on the 100mcg but I have been on it before without any problems. The reason was it that as I have heart palpitations he thinks its essential that I stay on a low Thyroxing just in case the palpitations get worse. I am a total thyrectomy case so the increase was welcome!
