loss of appetite?

Brett • Wife, Momma to Ben, Fur Momma to Tank, Squatch, and Mojo.
I'm 2w1d PP and have absolutely 0 appetite. I had a C-section and thought that if I cut back on my pain meds that would help. I'm completely off them now (don't need them of course)  but my appetite isn't back.
I need to keep a breast milk supply up since I'm exclusively pumping, but I just DO NOT want to eat. I have to make myself, but I just don't feel like it at all. any one else have this problem? How do I overcome this?
