Nightcap — Middle of the Night
Nightcap is the stage most hangover products don't have. Alcohol rebound hits at a predictable point in the night, and that point is when the protocol's second-biggest intervention window opens.
What this stack does
Nightcap handles the predictable 3–4am rebound: GABA-A withdrawal, residual acetaldehyde, and sleep-architecture collapse. Same Tier 1 acetaldehyde stack as Afterburner, with glycine and magnesium weighted toward sleep re-entry.

Mechanisms
Why this stage exists
The 3am problem
Drinking alcohol enhances GABA-A receptor activity, which is why it produces sedation. Your brain adapts by reducing GABA-A sensitivity and upregulating glutamate signaling. When alcohol clears — which it does faster than most people realize, roughly one hour of blood alcohol per standard drink — the inhibitory effect drops away while the compensatory excitation is still in force.
Net effect: you wake up around 3–4am, your heart is beating a little faster than it should be, your mind is racing, and sleep feels unavailable. This is GABA-A rebound.
Deep science · Why Nightcap — Middle of the Night is built this way
What Nightcap does
DHM is the lead here — it has measurable GABA-A activity and blunts the rebound. Glycine provides direct inhibitory neurotransmission. Magnesium modulates NMDA receptors, dampening the glutamate side. The acetaldehyde trap ingredients keep running because there is still residual acetaldehyde contributing to wakefulness.
Preventive option
You don't have to wait for the 3am wakeup. If you know from experience that you'll wake up — heavy drinkers almost always will — you can take Nightcap before bed as a preventive dose. It's the same formula; the stage name refers to the window it addresses, not to the hour you're awake.
