Nine months was rough for me, too...it's a little like being reborn, maybe? We're programmed to that time period from the beginning...
It got better. Calcium supplements with zinc and vitamin D seemed to help, but getting a doctor to look you over is always best. You could have an underlying condition like hypothyroidism that needs meds.
