...if you're chronically dehydrated - as most people are - then your body is constantly in "emergency mode" and continuously rationing water to protect critical functions.
Cayenne is a Godsend BUT if you keep using it to overrule your body in its attempts to properly ration what little water it is able to extract and distill from the foods you eat and the non-water crap you're drinking in order to protect your critical systems and keep you alive in the face of your refusal to drink plain water...what do you think is going to happen?
If you have indigestion? Then you are well and truly dehydrated - and have been for quite some time - and you're almost certainly malnourished due to the foods caked on and blocking the inside of your digestive tract due to the body having to suck the water out of it just to get enough to keep you conscious and your heart, liver and kidneys functioning for as long as possible.
Drink your damn water, people! Get your phone, open your clock, click on timer", set it for 1 hour and start it. Every time it goes off during your waking hours, drink a half cup of water and restart the timer. Or start with even just a quarter cup of water. Not juice, not tea, not so-called "Smart" water - Just plain, cold water.
Or don't - it's up to you - 100% your choice - but understand that under such circumstances, cayenne can only function as a stopgap by taking down your body's defense of rationing what little water it can steal from your gut - probably by sucking it out through the holes in the caked on matter in your gut - holes that are almost certainly created by parasites that are almost certainly drilling those holes and, thereby, keeping you upright and conscious - I.e. alive and conscious enough to get you to a watering hole.
