I have haschimotos. Have taken synthroid and cytomel for 9 years with no problems. Until recently, gained weight and losing hair . My doctor took my dose from 75 to 88 to 100 and 15 of cytomel. I asked to switch to naturethroid due to so much hair loss and sudden weight gains Doctor put my on 2 grains. I’ve been on it for 3 days. Any idea why i have no energy and headaches? I really want to switch back. I’m an educator and need energy for my kids at school. Should I give the naturehtroid more time since it has only been three days?
