HI
Coke is brilliant for gut rot. Used it all the time during my party years for hangovers, but on more serious note it is the phosphoric acid in the coke that sorts the gut rot out and the bubbles. Has to be proper coke though, not the diet sh*ite.
As for gut rot, funny how that crops up a lot on here.
Just as a thought, have you considered gallstones? Yes, i am obsessed with them, but i was fobbed off for 4 yrs with 'gastritis', ibs, constipation etc. My GP humoured me when i asked for a scan to 'check' , he was convinced i didn't have them.
Low and behold a bag full of large marbles on scan. After i had it out, the surgeon said it was rancid and had been years in the making. Funny how all my 'gastric' symptoms disapeared after it came out.
