I think serotonin excess from eating too much tryptophan from natural sources (protein) is highly unlikely. Particularly in the brain (most serotonin is in the gut). Those states of an extreme sedentary mood which are spoken of in your article certainly don't need more relaxation. The authors seem to fear serotonin therefore. But serotinin is one of the exitatory brain hormones. (See Flanagan at http://www.usvitamin.com/pharmacy.htm ) My guess would be 1.to look for other reasons for the effects (minerals etc) 2.a lack of dopamine The "Pharmacy"-article above describes this a little.
