I take Prilosec once a day, and after I posted that last night, I did a little more reading on PPIs and Prilosec in particular. From everything I read, it sounds like you're right, the acid is the culprit, and as such, I took a second Prilosec last night. Going forward, until I see the doctor's office again, I'm going to take it twice a day and see if that helps. While I haven't felt a change just yet, I'm hopeful that this will fix it. Being "hungry" sucks!
Though I read it time and time again, I'm still surprised that the recovery period is very quick for some people. I went back to work a week and a half after the procedure and could have gone back earlier but opted to have fun at home. My only challenge has been/still is an anesthesia hangover, where I feel fuzzy or groggy from time to time. At three weeks out from my surgery, I still feel the affects just not as frequently. I wasn't prepared for that at all.
MicNic, good luck with yours, you won't regret it.
