I started taking 1/4 grain of Naturethroid two weeks ago. I increased it by another 1/4 today which was taken at 6am. Not long later I felt very hot and my heart rate seemed to be faster. I wasn't able to take my temperature, as my thermometer has broken. My pulse at 9.30am was 72. Throughout the day I have been feeling more and more hypo. My pulse at 4.15pm was 58. I have absolutely no energy, brain fog, chest pains and heart palpitations. Please can anyone advise why I should feel like this after an increase? Also, should I go back to 1/4 grain tomorrow morning and then in a few days or a week add a tiny bit more, so that I'm taking 3/8th grain?
When I was on Levo I only took 32.5mcg, as I couldn't tolerate it any higher.
