my doctor prescribed to me liquid Zantac for 30 days 2x day. Yesterday morning woke up to empty bottle and being a holiday I couldn't get it. So today I called and and had it refilled. But when I woke up this morning I had bad Relux ( just guessing cause Ive never had). It was a burning feeling at the top of my throat downward. So around I picked up my prescription right away.... took it. And for some reason the burning is coming and going. I don't really feel like eating, just drinking water. Is this reflux or something else?????

Yes, reflux. It might take trying a different medication. Try sleeping propped up a little until it gets controlled, don't eat before bedtime.

You can also take a liquid antacid like Gaviscon, it's OTC
