Protonix

I have gotten severe bloating since being on Protonix. I don't have the burning and diarrhea I had with Prilosec and Prevacid but wondering if this is the problem. I am putting on weight as well. Haven't been this heavy since I was pregnant with my daughter in 76. I have other issues going on physically, but this has gotten worse since being on the medication? Also on Crestor, Singulair. Taking vitamins and extra D. I find the best relief I get is from Gas X. It has been a life saver, now wondering if I should go off Protonix as I still get a burning stomach, and can't afford the extra weight. UGH!!!
