I would get heartburn so bad Itd makes me throw up. They prescribed me a heart burn pill I take once a day, (safe while pregnant) haven't thrown up since. But before I got them I'd drink half a cup of warm water with half a lemon squeezed into it. Sounds like it wouldn't work but it does In less than like 5 minutes, it also gets rid of nausea, and instantly wakes you up. I don't get heartburn anymore but I drink it to wake up and start my day.
