My rebound lasted approx 6 weeks. I think I'm finally coming out of it (I hope). Yes, it was hell!
I have been on and off ppi's for about 15 yrs, however I took them daily over the last 2 yrs. Not sure I'd ever go back on them, as I choose to try to control symptoms with diet, supplements, tums, carafate and somtimes zantac.
