I started taking fish oil 4 years ago because I had some pain in the thumb joints. Within 6 months of taking it I decided to go to college (I was 40 ish at the time). A short time after that I was watching a "brain" doctor on PBS (can't remember his name) and he was saying how it helps with ADHD - I completely agree. It didn't do much for my physical hyperactivity but it did a lot to help my mental focus. Also my "ADHD" is self diagnosed, partly because of that tv program. When I went to my doctor she referred me to specialist for testing but then my health insurance refused to pay. At first I was pissed but I'm thinking in the long run they did me a favor.
