Hmm, interesting. I'm sorry that you are suffering.
It doesn't sound like what I experience though..no nausea or inability to eat a lot.
Just burning inside my stomach. The same burning that I feel in other parts of my body affected by neuropathy.
I have never done well with anti depressants, but I'm happy that zoloft helps you.
And yes, soda is horrible for your health

When you find a better solution, I'm sure you will switch over.
I smoke ciggys, so I'm not one to talk!
Tomorrow I'll try to note if it is worse when I eat. That could be an important clue.
