I was on this for 12 months, and thankfully was able to stop it after that. I feel my issues were with the beta blocker. Once I went off them, digestive issues lessened. Cardiologist yesterday didn't believe that the meds were the issue re egg intolerance, but suggested that it could be related to my recent flu vaccination. Hopefully the intolerance will dissipate. Feeling better on this new medication regimen. I hope you find someone who can give you some answers. Don't stop looking for them.
