That's interesting about the antacids. I actually bought a bottle of Betaine HCL around the time I saw the naturopath, which is about 3+ months ago. But hesitated to take them because didn't want to repeat the mistake with Prevacid where I'm trying to treat something that has no conclusive test result to prove that I actually have a certain condition.
That said, I started taking 2 tablets with every meal 2 days ago, haven't notice too much difference in terms of reactions so far. I also noticed that on the bottle it says to only take it for only 12 weeks. Did you continue to take it beyond the 12 weeks period?
