For many of those suffering from depression, SSRIs don't provide any benefit just by increasing serotonin, but rather through the downstream effects of serotonin receptor activation
Only a subset of depression patients actually present low serotonin
Other issues like reduced neurogenesis factors, elevated neuroinflammation, skewed GABA/glutamate ratios, etc, are present in the majority of cases
Activation of 5HT1A and 5HT2A receptors seems to be responsible for much of these effects
Research suggests they mediate changes in inflammation and BDNF levels long term
SSRIs have even been shown to provide analgesic effects, likely through their effects on endorphin levels
In the future we'll likely find ways to circumvent the serotonergic pathway to achieve these same effects more directly
Personally I hope a greater emphasis is placed on nutrient and methylation therapies, but we'll see

As I understand it babies crying constantly is a fairly modern phenomenon
In previous generations when a baby's cry would have been a safety liability, mothers would use techniques like holding the babies nose to train them not to cry at a very young age
And even into the late 19th and early 20th century it was very common to give babies alcohol and/or opium preparations to calm them
Let me expand since some of you are responding without actually reading this:
The key word here is constantly
Of course babies have been crying since the beginning of time, but historically cultures have minimized this in different ways that aren't employed today
Cravings are almost universally associated with a combination of low dopamine, low GABA, and elevated glutamate and cortisol
The endopioid system seems to play a role as well, unifying both dopamine and GABA in brain regions associated with pain perception and positive reinforcement
Managing cravings at the deepest level means understanding this well enough to correct any inbalance necessary
For example: managing stress, avoiding alcohol, avoiding activities like watching porn that desensitize dopamine/opioid receptors, avoiding hyper-palatable foods, etc
Asking a dermatologist if you should get daily sunlight exposure is like asking an atheist if you should go to church every week
In dermatology, one of the worst things that could possibly happen to you is skin cancer
In medicine in general, skin cancer is not common compared to other cancers or metabolic issues, and not very fatal, especially if caught early (even melanoma survival rate is 98+%)
On the other hand, daily sun exposure actually reduces risk for many other types of cancer, heart disease, and many other health issues
Skin cancer risk is increased by sunburn, NOT sun exposure, so as long as you don't burn your risk of skin cancer is not increased
The idea that cultures that use entheogens for the purpose of religious experience or enlightenment are not practicing "real spirituality" couldn't be further from the truth
All religion has roots in shamanism, it's only in more recent history that other religions have replaced shamanism with non-psychoactive sacraments
This is an excellent lecture that expands on this point:
There's nothing wrong with any religion, with or without the use of substances, all can provide genuine religious experience
The issue we're seeing in Western society is that because the experience of shamanism isn't available, it has been co-opted out as a tourist attraction
For a few months now I've been experimenting with microdoses of naltrexone, an opioid receptor antagonist
I'd like to unpack some of the benefits I've noticed and the most likely mechanisms through which it works
Naltrexone works through two primary mechanisms
1. antagonizing (inhibiting) the opioid receptors, most potently the mu opioid receptors which are responsible for the euphoria and pain relief from opiates and endorphins
