Natural Highs by Holford and Cass

I was interested in this book because I felt a healthy pick me up might be nice, and curiosity got the better of me. I don't know what I'd expected, but the recommendations are to take an awful lot of expensive supplements.

Kava, NADH and S-ame are allegedly herbal mood enhancers, which might be worth a try, a powerful multi-vitamin and mineral should ensure you're not blue because of nutritional deficiencies. Omega 3 is a recommendation that I include in my daily diet anyway.
