I don't think that's true. The reality is sick people would do anything to get well but I speak from personal experience still getting better from my own health issues 2 yrs later, that it's not possible to believe in miracle cures anymore, so that's why when someone says "just do this and you'll get better, I promise" you kinda roll your eyes and go yeah right, heard that 100x already. Not saying you don't have useful knowledge to impart on the OP, or that your advice won't work, but just that this is why people think this way. Like just the other day someone said "Just megadose Niacin man it will solve all your digestion and gut woes" well again, I've been here 2 yrs and still unwell so it's hard for me to believe this, considering this is just one of 100's of advice people have given me over the past 2 yrs, so yes, of course I'm skeptic lol. The advice may very well work, and it is quite possible I might try it in a week or two, but again, when you've tried 100 things already, you start to lose faith that #101 will finally do it lol.
Not to sound argumentative but I was just explaining what my experience has been, not claiming to know how most people behave. I literally knew of a diabetic who had their leg cut off and then years later died because they wanted to drink coke and continue to eat sugar. I have multiple stories like this. I think we agree though, 100% that it's difficult to take advice seriously when there is so much random, contradictory, and confusing advice on the board.
