I hate to be the one to throw a wrench in any works or anyting, but ...
When I got put on anitdepressants -
it was around the same time my thryoid began shutting down.
I experienced what I consider extreme weight gain during that time as well.
I understand what you're describing as a kind of unstoppable munchie-hunger...
which I NOW understand was my body screaming for energy
that it USED to get though food.
I just finished reading this book on hypothyroidism, by Mary Shomon.
I think it doesn't matter now what happened first
thyroid disease
or antidepressants
Because this book helped me understand that it is amazingly COMMON for early thyroid disease to be misdiagnosed.
And no matter what I did, or didn't do -
I could not lose a single pound,
and to top it off - continued to gain.
Adding insult to injury.
I am not saying that I know this might apply to you - not at all.
But if I can save anyone the discomfort and misery I've just gone through - for almost two years before a diagnosis- I'm going to try.
