I went to the GP because I was getting migraine headaches. He did a blood test asking the lab for tsh, t4 and t3 but they only did tsh which was 3.7. The GP told me to increase my dose from 25mcg a day to 50mcg a day. He said I could do it gradually if I wanted to, having 25 one day and 50 the next.
I am still only taking the alternate day dose as the more I take the more tired I feel. I tried 50 a day for 3 days but couldn't function as I felt too tired to function.
