Omeprazole

i’m attempting to do a 14 days or more of omeprazole. It worked great the first few days taking it 30 minutes before breakfast and 30 minutes before dinner. not sure why it works so perfectly the first three days and now doesn’t seem to be working, hardly at all. this is the exact same result I had last time I took omeprazole that last time I stopped after 14 days or so and I was not having much problems with LPR for awhile. that was several months ago, so my symptoms recurred. I’m trying to do a reset. just doesn’t make sense why it would stop working after three days. i’m 65, healthy foods and not overweight. I eat healthy, always read labels, but I’m not on any special diet.
