Just thought I would write this to warn people. I went into hospital for a back operation and had a racing heart and slight pain while recuperating. The nurse went out and 2 minutes later somebody came in with an ecg machine. After that they went into overdrive and had an ambulance take me to another hospital with a cardiology department. Was there for 3 days and while there they put me on statins as my cholesterol was up slightly. Came home and improved from all the other stuff and then a week ago I had half a grapefruit. Just did not think for which I paid dearly. I was in excruciating stomach pain, then the next day I could not stop being sick, every half an hour. They wanted me to go to hospital but I did not want to go. It finally calmed down a bit on day 3. I still cannot eat much as it makes me sick. Just thought I would warn people as it was the week from hell.
