I was on 100mcg of Levo when I got an appointment with an endo at my request. He told me to reduce my Levo to 75mcg and take 10mcg of T3. This was over 3 weeks ago but I haven't noticed any benefit yet. Is it too soon or is the amount of T3 too small. I notice that the lowest dose you can buy is in 20mcg tablets and they are so difficult to cut in half. I've tried a pill cutter but that just shatters them, so I'm using a sharp knife and trying not to waste too much! Thank you.
