I also have that and a glass of cold water also makes it disappear.

I have them frequently. If i drink a glass of COLD water they dissipate. Also, try zantac.

Ask your doctor to organise a gastrophtrophy, mine wasn’t closing at all causing bad reflux etc. I had op to fix, feel totally different much better but now must eat slower,I often use a teaspoon and stay away from some foods.
