N.M.
I feel your pain. My first pregnancy I had this really bad. At some meals I would eat and eat.....and eat, until food was so pilledup I could feeling inching it's way up my throat. And still, I felt as if I was staving. That horrid void of emptiness that never seemed to go away. There were times when I actually started to cry at the table because I was so hungry but knew I couldn't take another bite.
Finally I told myself, enough. I knew I would not be satisfied so after I ate a good, designated meal I stopped eating. Hungry or not, I knew I had enough food and just suffered through the discomfort. And yes, it was hard. But I knew I had to disapline myself or gain 300 pounds trying to satify a hunger that would never end. I did this for 5 months till the baby came.
I just think sometimes the hormones messup the body so much that the "turn off" switch for eating gets broken. I'm pregnant again (8 months) and luckily it hasn't been too bad. I have had a couple of days when I can't get satisfied, but those are few and far between. Today, is one of them, however. :(
The only thing I can offer is this. If smell is a big issue with you, and you're staving, look for things with little to no smell. String cheese for protein worked for me. And pain steamed rice to fillup. Also, talk to the doctor. If it's indeed a hormone thing, perhaps he can help. I never told my doctor, I just suffered through it. But that's me.
I'm so sorry you're going through this. I truely know what you're going through and hope you find a way out of it. Good luck!
