Actually, I'm going to try and go back to the doctor after trying Prilosec OTC for the past few months. At first, it seemed to work fine, but I've begun gaining weight and the flutters are back, occasionally as bad as before. I haven't changed the way I eat or slacked off on my exercise, so the weight gain is somewhat unusual. I think I'll see if he'll just put me back on Nexium for as long as he's comfortable doing so and see if I heal. Chances are, my esophagus or the valve at the lower end of it is inflamed and just needs some months to heal.
