Cold turkey is too fast with Omeprazole. Last month I was on a diet, eating small meals, none of the things that give me bad GERD like ice-cream, orange juice, etc. So I thought it was time to get off the Omeprazole.
Here is how you do it: Open the capsule and count all the little white beads. Throw away three of them, close the capsule and take what's left. After a week or a few days if you're feeling fine, throw away six of them, etc. until you are down to just about three beads at which point you can quit.
I did this method and was completely off Omeprazole for about a week -- when I blew my diet, stared binging and had to return to the drug.
I'm going to start over soon, but first I need to get control of my food.
