Developed it after being overdosed with Cortisone after a foray into the kitty litter at a track day in my 60s but with hindsight had it since the Trident days and various exposures to neurotoxins.
Still paraglide in my 70s. Strictly avoid wheat especially in sauces and chemically extracted cooking oils although if I can get proper virgin olive oil no problems.
Proper diet, avoid liars in restaurants, read the ingredients and drink as much as you want and you won’t have any problems.
Stress doesn’t affect it.
You will be surprised at the number of products that have wheat ingredients...especially frozen chips and soy sauce. I avoid glucose syrup too?
Cook using gram flour and Fufu..from ethnic shops.
