I have been on different antidepressants and anti anxiety medications for half my life. I know this slows my gut down and it was slow to begin with. I take pericolace daily to keep me moving. About 2 years ago I began to have methane gas belching and vomiting episodes and went to my GI. After 2 colonoscopies and one EGD I have zero answers. Everything always looks normal. Over time my symptoms have changed but definitely remain persistent. I have the methane gas and abdominal discomfort, sometimes diarrhea and mouth sores with a loss of taste for a day or two. It seems the healthier I eat the more flare ups I have. Anyone else out there have similar experiences?
