I am going through the same exact thing.
I cannot eat a full meat, otherwise, I puke.
Last week I had breakfast before coming to work, I think it was Monday. On my way, I had to stop on some street and vomit XD! Gross! LOL.
Anyways, what works for me, is to distribute my food throughout the day. That way I don't get too full, bloated, or vomit.
