"I think many times we're doing these temporary fulfillments of desire because of brain chemistry."

I think there are a number of ways of dissecting anything, including the 'nature' of desire. For my way of thinking, a 'desire' corresponds with an inner sense of 'lack'. In other words, the desire is an outwards projection of an 'inner hole'; or the seeking of fullFILLment from an external source.

"If it's a desire for something that one truly needs it may not re-emerge, but if it's about righting the air/fuel mixture in the brain, then it will be never-ending causing us to do physical things to sate it."

I make a distinction between desires and needs as perhaps two sides of the same coin. Perhaps the Desire is this sense of need which seeks gratification on the outside (never ending seeking/excitement/disappointment; disguised through control or manipulation; 'needy'); and perhaps the Need is more fundamental. We have basic needs as kids (attention, protection, mirroring - see image below, from Healing The Child Within by Charles Whitfield) and for most people (80%+??) these needs are NOT met as children. This is extremely traumatic and it leaves a gaping hole which seems to get bigger into adulthood. This hole gives birth to desire - the urge to seek gratification (to have those unmet needs met by the outside world, partners, friends, animals blah blah - and by force or manipulation if necessary).

These unmet needs from childhood can be met in the present moment. This is an internal process which acknowledges 'desire' and the urge to seek gratification, but it takes responsibility for oneself, understands wtf these unmet needs are and what their effect on current state of being is. Once understood at the psycho-emotional level of one's life experience, these needs are potentially then able to be met by the person him/herself without seeking gratification on the outside. The connections between one's unmet needs from childhood and the seeking of external gratification (sometimes heavily disguised, sometimes naked) become clear.

"With the gratitude technique in this article, one may be self-administering a dopamine hit without having to do something external to achieve it."

Sure, that's what I meant by "The hacks are great, and they calm the burning fires." However I think this is also a question of how deep one wishes to go. Applying a 'fix' brings temporary solace, but the underlying issue is still present, beneath the surface and influencing in the background - the malaise. Reaching deep inside to the core of the issue allows for a process of reprogramming/release. One is able to actually free oneself from much of this malaise - not as a balm, not temporarily.
