Yes, it seems my acid reflux is over the roof since my gallbladder surgery. I was on prescription strength Prilosec and it was fairly under control. Today I changed to Prevacid and it seems to be helping better but I do have a slight headache. I guess would rather put up with a headache than the acid bath washing up against my throat. Let us know how your outcome is with the Nissen procedure. The surgeon offered to perform the Nissen for me at the same time he pulled out my gallbladder but I got scared and didn’t take him up on his offer. I hope I didn’t make a mistake and live to regret it.
