Just to be clear: I hope you noticed my play of words there . I am absolutely convinced about the effects of omega3 - especially as I have avoided fish my whole life due to a serious allergy (a real one, not something I invented; my throat completely closes up and I get a horrible rash inside my mouth minutes after eating some types of fish).

A good read for me was "The Queen of Fats". It made me understand that it's about more than just fish consumption. I don't think it's a cure for all, but I do think that our diets are lacking in a number of ingredients (omega3, magnesium, B12 for many etc) that can be supplemented in a safe and relatively cheap way (although good fish oil is rather expensive).

But just thinking about omega 3 will not be enough.
