okay so I'm having worst acid reflux and indigestion ever for the last month non-stop even when I eat nothing. Its causing me to cough really bad and Its eating away at my vocal cords and I'm for sure getting acid in my lungs. and can't really eat anything. So I went to the store today (before reading this post) and bought Betaine HCL writh pepsin and under that it says known as trimethylgycine (TMG) and on the back it says: Betaine hydrochloride (from sugar beets). SO what the heck am I taking???! you said the TMG that you recomend is from beets so wouldn't this be good??? and like 10 mins after taking it I feel some heat in my head weird! I have taken tons of swedish bitters (alcohol free) in the past when I wasn't having acid reflux and loved them but now that I'm actually having a problem with acid its not working.
