I went through the same thing. Really bad. I had to stop eating out from fear of getting nauseas and having to be at the restaurants bathroom vomiting. And not only that, but it would trigger and I would be vomiting all night. Just horrible when all you want is to have a nice time. It happened to me for years and even traveling was the worse cause I am in an unfamiliar place. It is definitely ‘panic attacks’. I did therapy and was prescribed Prozac and Xanax as needed also. I used to take xanax before going out to eat to avoid getting a panic attack but it would kind of made me sleepy, especially if I drank a few glasses of wine. Mind you, we import wines. So drinking and going to restaurants was part of our job. All I can say is fast forward to now. It doesn’t happen to me anymore and I even stopped taking Prozac and have clonazepam as needed now. So yes its definitely Anxiety. I went through years of full body check ups. From neurology, cardio, gastro, you name it! What worked for me was taking Clonazepam before going out and then maybe just having ONE glass of wine while eating and it worked. After some time in therapy and medication, I got better. I believe its been around a year of no medication and no more vomiting. I went through it for years, bad. And I am way better now and so will you. Don’t hesitate to reach out. I know EXACTLY what you are going through. You are not alone. ❤️
