I saw this DC a while ago for sleep problems. He gave me 5htp suppositories. Not only did it give me serotonin syndrome but I found out later from a scientist ( a real scientist, not a quack chiropractor) "The fatigue produced by “over-training” is probably produced by a tryptophan and serotonin overload, resulting from catabolism of muscle proteins and stress-induced increases in serotonin. Muscle catabolism also releases a large amount of cysteine, and cysteine, methionine, and tryptophan suppress thyroid function (Carvalho, et al., 2000). Stress also liberates free fatty acids from storage, and these fatty acids increase the uptake of tryptophan into the brain, increasing the formation of serotonin. Since serotonin increases ACTH and cortisol secretion, the catabolic state tends to be self-perpetuating. This process is probably a factor influencing the rate of aging, and contributing to the physiological peculiarities of aging and depression." When I had problems Dr. Cafarelli got defensive and ped me as a patient. Yeah you really want to go to this lunatic when you are sick to deal with his ego b/c you don't have enough stresses in your life.
