I've been seeing a gastro doctor for four years and I'm WORSE since... Wish I'd bothered to try and heal myself because now I can't eat anything or go a day without pain and cramping.
Gastro doctors suck and get bigger paychecks than anybody on here so I don't know who you're accusing of being 'greedy'
At the very least you don't have to be a know-it-all dick about it.
