I AM A 77 YEAR OLD MALE WITH A HISTORY OF HEART DISEASE; I.E., OPEN-HEART SURGERY PLUS A TOTAL OF 9 STENTS, 4 OF WHICH ARE AORTIC. i AM ALSO DIABETIC, TYPE 2 UNCONTROLLED. I HAVE HAD GIR FOR ABOUT 3 OR FOUR YEARS NOW, UNDER CONTROL WITH OMEPRAZOLE 20MG. FOR SOME IDIOTIC REASON I ARBITRARILY DECIDED TO DISCONTINUE TAKEING THE OMEPRAZOLE A COUPLE OF DAYS AGO, SINCE I HADN T HAD ANY GASTRIC ACID EPISODES IN A VERY LONG TIME. BIG MISTAKE! I VE BEEN FEELING VERY SICKLY ALL DAY, SO AT APPROX. NOON I ATE A TUMS TABLET. THAT DIDN T WORK VERY WELL, SO AT ABOUT 5 PM I FINALLY TOOK A CAPSULE OF OMEPRAZOLE. WITHIN ABOUT AN HOUR I HAD VERY WATERY DIARRHEA AND AN EXTREMELY ACID STOMACH. WITH THIS LEVEL OF DISCOMFORT, I DOUBT THAT I LL BE ABLE TO SLEEP TONIGHT, SO WHAT SHOULD I DO NEXT. I M AFRAID TO TAKE ANOTHER CAPSULE. THANK YOU
