Anyone know why I would vomit almost every time I have a bowel movement? I don't have symptoms of obstruction or even constipation. I can find nothing in my diet that would cause this, though I did up my fiber intake and water intake thinking it might be part of it. Actually, not water intake, fluid intake. drinking water is an immediate trip to worship at the porcelain altar. Which annoys me greatly. Any ideas/suggestions appreciated. I did do a "cleanout" with miralax and benefiber a couple of weeks ago, but it didn't help at all. In addition to the other problems, I do have IBS also. It isn't the virus, because it has been going on for about two-three months and the virus is on about day 12 for me. No one else in the family has this either. Sorry if this is too gross. I just am sick of barfing.
