Has the Lemon worked? I have the same thing but sometimes it's immediate diarrhea instead of vomiting but each meal is the same. They diagnosed me with GERD. But once again no pills have helped. Years ago a doctor had put me on flagyl 500mg 3 x a day. That seemed to help. So going to ask new doc to so the same. Have a lot of belching and a lot of gas as well. Very embarrassing. Let me know if anyone here's of anything that works. I am going the flagyl root again.
