I have been on cytomel and synthroid for years and have been gaining weight since. And a lot. I always feel terrible but when i go to my doctor he says exercise more. Currently i go to the gym 5 days a week.isnt that enough?Its really affecting me mentally. Any suggestions. I look horrible and embarrassed to look like this. As i have been reading other peoples situations, seems like they all have the same complaints. Going to go off meds and see what happens... Help...
