I've had heartburn for alittle over a day due to a new cold medicine I was taking. I'm certain it's the meds. I stopped the meds yesterday evening. Is it common for heartburn to last that long?

I had a hiatal hernia so I had it last for months. I found drinking hot tea, or even just a glass of hot water when tea wasn't available really helped. (No coffee, because there is too much acid in it.) Adding a small amount of baking soda to hot water can really work wonders. If  am not careful now it can kick back in and last for days.
