I have never been a drinker. Most people assume that means I didn’t like the taste or that I grew up in a strict household. The truth is simpler and more human. I was adopted at birth and raised as an only child by two functioning alcoholics. Nothing about that environment made intoxication look appealing. But my avoidance wasn’t just moral, cultural, or observational. It was neurological.
Alone with nobody to turn to as a youth surrounded by trauma, I learned at a young age that I never wanted anyone to have control over me again.
I never wanted my mind even slightly fogged. I never wanted my reflexes slowed or my instincts diluted. Instead of playing with toys, I was busy learning that the only person I could rely on to keep me safe was myself. So I wasn’t willing to surrender that responsibility to anything poured into a glass.
What most people don’t realize is that decades of trauma exposure hard-wire the nervous system into a precise and efficient machine. Even after the trauma is processed, integrated, and genuinely healed, the body retains a surveillance system built for survival. The alarms may not blare the way they once did, but the wiring remains sensitive. And for some of us, that sensitivity shows up in ways that most clinicians, family members, and even trauma survivors themselves don’t always connect to the past.
For me, the oddest and most consistent example involves alcohol. Even now, with a life that bears no resemblance to the chaos I grew up in, I can take a single sip from someone’s glass, and I won’t sleep that night. There is no sedation, no warm heaviness, no slight relaxation. It doesn’t take a drink. It doesn’t take a shot. It doesn’t take a buzz.
One sip is enough to flip every internal switch back to alert. I become fully awake. Energized. Almost electrically aware. It is a response that confuses people who’ve never lived inside a hypervigilant system, but anyone with a trauma-wired nervous system will recognize the physiology immediately.
People think alcohol calms the body. Neurochemically, that isn’t what happens. Alcohol depresses the central nervous system for a moment, then the brain compensates by releasing excitatory chemicals meant to restore equilibrium. In a stable nervous system, that rebound occurs hours later and usually manifests as restless sleep or dehydration.
In a trauma-exposed system, the timing is different and the threshold is microscopic. The body doesn’t wait for the sedative effect. It interrupts it. It overrides it. It refuses to allow the individual to go offline in any capacity that could compromise safety. That override is not a choice. It is an autonomic decision made by a brain trained to stay alive when the room gets dangerous.
The reactions that most trauma survivors describe—light sleep, sudden alertness, a spike of anxiety after drinking—happen in me instantly.
- The body still remembers what it cost to be slowed down while someone else’s anger was accelerating.
- It remembers what it meant to be a child in a home where the adults were unpredictable, emotionally unavailable, or intoxicated.
- It remembers what it meant to calculate survival in real time by reading micro-expressions, tone shifts, footsteps in a hallway, and the subtle changes in the air that came before an eruption.
A body shaped by that environment will not casually allow itself to be impaired, even decades later, even when the threat is long gone.
Trauma conditioning is not just psychological. It is sensory, chemical, and neurological. The nervous system learns faster than the intellect. It learns in circumstances where sedation was dangerous, and it keeps that lesson. Some survivors avoid alcohol consciously. Others avoid it subconsciously. And some, like me, don’t avoid it at all; the body simply rejects it. The response is automatic: stay awake, stay aware, stay capable. The evolutionary logic behind it is flawless. It is a brilliant adaptation, even if it is inconvenient in adulthood.
This is not a moral argument about drinking or not drinking. It is a physiological explanation for a pattern many survivors have never had language for. Some trauma-exposed adults discover they cannot tolerate anesthesia in the typical way. Some become paradoxically stimulated by medications meant to sedate them. Some lie awake for hours after a single glass of wine. Some can’t sleep after CBD or melatonin. And some, like me, can take one polite sip at a party and spend the entire night wide awake with a nervous system that refuses to soften.
It is not the alcohol that keeps us up. It is the history. It is the memory in the body that knows what vulnerability once cost. It is the survival reflex that interprets any alteration of consciousness as a potential threat. Even when we feel healed. Even when we are safe. Even when no one is trying to control us anymore.
The response is not pathological. It is intelligence. A trauma-wired system does not relinquish awareness lightly, and that refusal is not something to be ashamed of or corrected. It is something to understand. For many survivors, the body’s rejection of alcohol is one of the last standing boundaries that kept them alive more times than they ever realized.
- Trauma teaches the body to stay awake.
- Healing teaches the mind that it no longer has to.
Both can be true at the same time. And if your system reacts as mine does, you’re not broken, odd, or overreactive. You’re trained. And your body is still doing exactly what it learned to do when you needed it most. That is, protect you from anything that could take control away from you.

Dr. Mozelle Martin is a retired trauma therapist and former Clinical Director of a trauma center, with extensive experience in forensic psychology, criminology, and applied ethics. A survivor of childhood and young adulthood trauma, Dr. Martin has dedicated decades to understanding the psychological and ethical complexities of trauma, crime, and accountability. Her career began as a volunteer in a women’s domestic violence shelter, then as a SA hospital advocate, later becoming a Crisis Therapist working alongside law enforcement on the streets of Phoenix. She went on to earn an AS in Psychology, a BS in Forensic Psychology, an MA in Criminology, and a PhD in Applied Ethics, ultimately working extensively in forensic mental health—providing psychological assessments, intervention, and rehabilitative support with inmates and in the community. A published author and lifelong student of life, she continues to explore the relationship and crossovers of forensic science, mental health, and ethical accountability in both historical and modern contexts.
