I have had Gerd since I was in my 20s only didn't do much about it. I was taking a handful of TUMS at night. Never had much trouble during the day but nightime was killer. I modified my food intake to nothing after 8. it got so bad I finally went to the doctor about it and they put me on previcid. as long as I take it regularly I am fine 99% of the time. that other 1% is when I **** up and have the wrong thing right before I go to bed or forget to take my meds. I have been on previcid for a very long time with no ill effects. Not everyone has a bad reaction. I eat what I want when I want and I'm fine as long as I take the meds
