After dealing with digestion issues for over 25 years, only by the grace of God did the true cause of my problems ever get diagnosed. Nowadays, I can eat anything without a problem. There was a time when I was on 40mg Nexium twice a day and still had issues even when watching my diet. My doctor told me I'd have to be on that stuff for the rest of my life. He was wrong! I haven't had Nexium, Prilosec, Prevacid, Axid, Pepcid, or any other acid reducer/blocker for over seven years. It was like a miracle when I was properly diagnosed and treated.
Bring on the MSG! It doesn't bother me.
