Reflux attack/episode after gallbladder removal?

So I had my gallbladder removed in November of 2015 because it was causing extreme nausea after every meal. Since then I've been on a knockoff version of lexapro 10mg. I've been great ever since.

So today I had half a beer and my hands started to shake for about an hour and a half. This had always happened right before an attack. So I had a chicken salad sandwich thinking this might help. Within 20 minutes my heart started racing and everything from my stomach to the back of my mouth was hot and I felt nauseous and dizzy like I was gunna pass out. I laid down and fell asleep for about an hour. I got up and went to the bathroom and had a bout of diarrhea which was a little green. I feel OK now and this is usually how the episodes would go before gallbladder removal except this time was faster and less nausea.

So my questions are, has anybody had the same symptoms? Does anybody know what this is? If so, how do you stop it or deal with it?

Thank you!

none of these problems, see your GI Specialist immediately

Yes i have similar symptoms to this. I had my gallbladder removed in September and i have had a couple of episodes of severe pain, shaking, going extremely hot and clammy. I find taking some kind of antacid helps but does take up to half an hour. My doctor says its due to fats not being broken down and causing reflux. I also find tomatoes can cause this too. Hope you find something that helps you x
