I have been told I need to take Prilosec ("for life"), along with Bentyl and a couple of other antispasmodics. Within the last few months, Prilosec et al is not doing same job. I am very bloated every day-Gas X helps but I take 3Xday. I can feel the food coming back up. I read Prilosec and Prevacid are about the same. What about Nexium-can it work better, cut down constipation, cramping, gas bloating, spasms?
