Sorry for triggering. It's weird though, I'm quite healthy actually, despite, you know, my "habits". Never had problems with the stomach or bowel system or that whatsoever. I do get the gout, but I read that can be related to my lack of melatonin production (I don't sleep much). It's also, the cola is acid obviously, so it lowers the body's pH which can make the uric acid crystals crystallize out in the joints. If I had normal melatonin, then the body will break down the uric acid before it can form crystals. But, I've got alkaline treatment for that and it works quite well, it usually clears it in half a day or so .
