I see lots of harmful "advice" pushed by supposed ADHD sufferers.
One time I saw an older ADHD sufferer trying to mentor a young person with ADHD by telling him to cut out preservatives and take up meditation.
Leafy Greens and Pay Attention are barely a step beyond vagina crystals and positive thinking, and its awesome that you think they worked for you, but people should be referred for proper medical treatment, always. Even if you add your other wins as supplementary options, it should never be seen to be something alternative to medicine.
