Beginning with diet. I have cut out all processed foods. I always buy organic and keep looking until I find it, or go without if it is not in season. I never eat deep fried foods and shallow fry keeping the oil temperature low. I only ever use EV olive oil, no other oil and never ever margarine. I try to balance my diet and have a small amount of alcohol, mainly red wine and a small tot of something before bed, just like my dad used to. I have never smoked so that was not an issue and don't understand why people do it, or indeed continue after a serous illness.
I take stress management very seroiusly and have read everything I can lay my hands on, including Youtube stuff. On the other hand I read as little as possible on what I find stressful. I use CBT techniques with a list of 6 stress lowering exercises I got from Youtube, to fend off panic attacks and they do work. I think everyone grossly underestimates the importance of this subject.
I try to get as much exercsie as possible, I know I am lazy, so I make it easy for myself. I cycle at weekends, I have built a small gym and my wife and I nag each other to use it more. I keep 2kg dumbells and 1.5kg ankle weights by the sofa and use them when watching TV. These have helped my arthritis a lot.
I suffer from cardio-gastic syndrome and do a "sit up" style yoga exercise to strengthen my esophageal sphincter, which seems to help and since this is stress related, I use the aforementioned techniques to assist.
Am I cured? no, but most of the time I am okay and feel all of the above help me in my quest for better health. But every day I read/watch everything I can lay my hands on and evaluate to the "n"th degree, interested only in the message, not the messenger.
