I've had nausea for 6 going on 7 years now and have tried everything out there. Sometimes you get a few hours of relief with pills, anti motion sickness pills work the best for me. Walmart has them really cheap. 100 pills for less than $7., Equate is the brand. I have also had some relief with Robinul. That's what they give you in hospital before surgery to dry up all your secretions. I haven't take that too often, only when nothing else works. Like Ginger tea, that helps sometimes, when I can get it down. Sometimes just putting a Tums in my mouth helps. I don't get heartburn often, but when I do it's terrible. I also take Zantac. I can tell when I need one of those, it's when my stomach is really empty, I also need to keep something in my stomach, every couple hours I need to eat something. I have to watch the spicy foods, that really gets the nausea going. Also watch that you go #2 at least every 2nd day or else!
Sometimes you just can't take certain meds.
