I am 12 weeks out today with no complications, feeling great, etc. I take Omeprazole 20mg every morning and have no history of heartburn or reflux (ever). I also take the Ursodiol 2x day for gall stone prevention.

This morning I took the Omeprazole, did my sublingual B12, then made a Protein shake (nectar Lemon Tea w/Benefiber and water), and took my Centrum Multivitamin (petite). Same as I do almost every day, nothing different. I was feeling fine. Then in the shower I felt really "excitable" like I'd had three cups of high-octane coffee. A few minutes later I got that horrible feeling in my chest similar to the sliming sensation. Next thing I knew I was vomiting the Protein Drink (brown in color) with a lot of yellow liquid as well. It did not hurt and I felt much better once it was over.

The same thing happened to me exactly a month ago while working out in the morning, though I was able to prevent vomiting then.

Does anyone know what this could be?!!? Other than these two times, I never vomit and always get down food/drink just fine. The amount of yellow liquid is what bothered me most.

My first thought is your gallbladder. I know that you are taking Ursidoil, but it may not have been enough to prevent a stone. Call your doctor.

When it happened to me, it was in the middle of the night and I vomited only yellow liquid. I was trying to stop my omeprazole and the yellow stuff was all acid and gastric juices. When I started on omeprazole again, it never happened again. Maybe you need it twice daily?

The yellow sounds like bile and it could be your gall bladder is not functioning properly. Call the doc about it.

Yeah, bile is the first thing that came to mind. If it continues, I would call the doctor. Good luck!

Thank you all for your quick replies. I called my doctor and it doesn't seem to be serious. Since it was a single incident, he's not concerned but wants to know if it happens again. He said it was definitely bile, but that is not always a bad thing. You do want the body producing some bile/cholesterol to break down fatty foods. I did have salmon last night which is one of the fattier fishes (granted, only 2oz). He targeted that it was because I was really moving a lot, going up/down the stairs in my house a few times, taking a shower. I was bending over to wash my feet when it came on suddenly. I'm usually sitting down or just walking lightly around the house during my morning shake, but today I had somewhere to be. The last time I had this sensation was similar: I had my shake a little later than usual and was working out with my personal trainer when I felt it.

So fingers crossed that is it and it won't happen again!
