Here is an article of RP to understand why too much of a good thing can be bad, especially when substitution drugs are used (SSRI)
Serotonin, depression, and aggression: The problem of brain energy.
Ray PEAT
=> Excess serotonin is deleterious (nerve damage and mitochondrial respiration). Too much of a good thing is bad, especially if we want to play the role of the alchemist in the brain!
Excerpt 1
Anyone who has been reading the mass media and watching television in recent decades is familiar with the use of tryptophan as a tranquilizer.
Tryptophan is easily converted to serotonin and melatonin in the body, and those substances are believed to be responsible for its sedative, sleep inducing, or tranquilizing effects (Hebenstreit, et al.; Allikmets & Zharkovskii(; Shelekhov & Val'dman; Winokur, et al.). The most popular kind of âantidepressant,â the âserotonin reuptake inhibitor,â is said to act by increasing the action of serotonin in the brain. Many people have read articles in popular science magazines explaining that a deficiency of serotonin can cause depression, suicide, and aggression. Estrogen is often said to achieve some of its âwonderfulâ effects by increasing the effects of serotonin. (âŠ)
Excerpt 2
Serotonin research is relatively new, but it rivals estrogen research for the level of incompetence and apparent fraudulent intent that can be found in professional publications.
This is partly because of the involvement of the drug industry, but the U.S. government also played a role in setting a pattern of confused and perverse interpretation of serotonin physiology, by its policy of denigrating and incriminating LSD, a powerful serotonin (approximate) antagonist, by any means possible, for example claiming that it causes genetic damage and provokes homicidal or suicidal violence. The issue of genetic damage was already disproved in the 1960s, but this was never publicly acknowledged by the National Institutes of Mental Health or other government agency. The government's irresponsible actions helped to create the drug culture, in which health warnings about drugs were widely disregarded, because the government had been caught in blatant fraud. In more recent years, government warnings about tryptophan supplements have been widely dismissed, because the government has so often lied. Even when the public health agencies try to do something right, they fail, because they have done so much wrong.

SSRI
The âserotonin reuptake inhibitorsâ are called the âthird generationâ of antidepressants.
Excerpt 4
To begin to understand serotonin, it's necessary to step back from the culture of neurotransmitters, and to look at the larger biological picture.
Serotonin and estrogen have many systematically interrelated functions, and women are much more likely to suffer from depression than men are.
Serotonin and histamine are increased by estrogen, and their activation mimics the effects of estrogen. Serotonin is closely involved in mood disorders, but also in a great variety of other problems that affect women much more frequently than men. These are probably primarily energy disorders, relating to cellular respiration and thyroid function. Liver disease and brain disease, e.g., Alzheimer's disease, are both much more common in women than in men, and serotonin and estrogen strongly affect the energetic processes in these organs. Liver disease can increase the brain's exposure to serotonin, ammonia, and histamine. It isn't just a coincidence that these three amines occur together and are neurotoxic; they are all stress-related substances, with natural roles in signaling and regulation.
There are good reasons for thinking that serotonin contributes to the nerve damage seen in multiple sclerosis and Alzheimer's disease. (âŠ)
Excerpt 5
The âserotonin reuptake inhibitorsâ âare presumedâ to have the same effect on the brain that they have on blood platelets. They inhibit the ability of platelets to retain and concentrate serotonin, allowing it to stay in the plasma. This uptake-inhibited condition is a model of the platelet behavior seen in multiple sclerosis and Alzheimer's disease.
Serotonin and its derivative, melatonin, are both involved in the biology of torpor and hibernation. Serotonin inhibits mitochondrial respiration.
Excitoxic death of nerve cells involves both the limitation of energy production, and increased cellular activation. Serotonin has both of these actions.
Serotonin activates glycolysis, forming lactic acid. Excess lactic acid tends to decrease efficient energy production by interfering with mitochondrial respiration.
Excerpt 6
Serotonin, like histamine, has its proper physiological functions, but it is a mediator of stress that has to be systematically balanced by the systems that support high energy respiratory metabolism.
The use of supplements of tryptophan, hydroxytryptophan, or of the serotonin promoting antidepressant drugs, seems to be biologically inappropriate.
