As indicated above, it doesn't really fit in a single comment on HN. But, very incompletely:
Dietary changes:
Current standard medical advice is a high fat, high salt, high calorie diet. To meet those criteria, they literally encourage people to eat junk food.
I did the opposite. I got very picky about food quality, salt quality, types of fat consumed etc. My focus is on nutrition and an anti-inflammatory diet, though saying that falls far short if what's involved.
Lifestyle changes:
I gave up my car and made other changes that reduce my exposure to chemicals my body doesn't cope well with. I do a lot of walking and I currently do freelance work from home to reduce my exposure to germs and increase my control over my work environment.
Health changes:
I've gotten off all medication. I used to be on 8 or 9 prescription drugs. After getting off of them, I took OTC drugs for years. I'm now drug free.
The hole in my lung has closed. My sleep quality is vastly better. My energy, mental clarity and mood stability are all better. I am less sensitive to allergens and chemicals. I get cut less easily. I no longer have chronic low grade nose bleeds.
It seriously doesn't fit in a single comment, but there's your nutshell version.
