>>I get these symptoms from EVERYTHING that is acidic
OK so we know its an ulcer.
First you need medicinal cayenne, there is a lot of cheating going on with hypbrid cayenne now.
Not Genetically-Modified-Organisms so it comes thorugh as organic but has had the active ingredient breed out.
I notice even oriental stuff is like that now.
The cayenne will seal the ulcers, some pain is normal with this and can be lowered by using betel nut, DGL or non irradiated Turmeric.
Scars are irrelevant at this point the ulcers are not closed, at the very minimum you should be taking SSKI though.
try and find a 40k Heat unit cayenne then move it to 100k when the pain stops. Conqee is a good delivery device since it keeps the carbs in the stomach for some time.
There is no point eating without cayenne since any food can and will get stuck in those ulcers.
Drink Vervaine tea to keep it all clean and in a day you should be fine.
