Best upset stomach remedy ever!

Every morning I awake with a sharp burning pain in my belly. It takes about an hour of walking around, stretching, and trying to use the bathroom before it becomes manageable. Usually I pop three to four Tums and chase them with a good chug or two from a Pepto-Bismol bottle (shout out Pepto!) I still have some residual dull pain that feels like my system is clogged. After discussing with some of my co-workers who noticed my daily predicament, one recommended a remedy that at first I raised an eyebrow and balked at, but eventually decided to give a shot, literally. She recommended taking about a 1 oz serving of apple cider vinegar. And not just any vinegar, it has to be unfiltered and has whats called "The Mother" inside. "The Mother" is a sort of cloudy snot-like formation, and all I know about it is that the Amish save it to start the next batch of vinegar. I woke up er the usual with an upset stomach and decided to try the vinegar remedy, and amazingly after the initial burn going down, completely settled my stomach. I have been taking a shot a day for a month or so and the difference is amazing. Who would think such a simple solution could work? I implore anyone suffering the same stomach condition as myself to try this now that I've given some background on the right kind to use. I use a brand called De Nigris. Please comment and let me know if this works for you, or if you have an even better home remedy, please let me know as well. Thanks guys!
