Five Sleepless Nights Off The Coast Of Alaska, And The One Question The Ship's Doctor Asked

She saved two years for the cruise and could not sleep on it. An unhurried Austrian doctor on Deck 3 asked what ten years of appointments never had.

Two sisters at the ship rail at dusk
My sister took this on night five. I had been awake for most of the previous four.

You know how everyone says the ocean rocks you to sleep? Fourteen days, my sister and I, Alaska, the trip we planned for two years. The ocean rocked her to sleep in nine minutes a night. I lay in the same stateroom, wide awake at 3am, doing the math on how much each wasted night had cost us.

By day five I looked gray at breakfast and my sister marched me to the medical deck, the way only an older sister can.

Deck 3, Dr. Brandt

The ship's doctor was Austrian, maybe sixty, with the unhurried manner of someone who has seen every kind of seasickness and none of it impresses her. Blood pressure, a few questions about the trip. Then she put the cuff down and asked the question.

"How much coffee, how much stress, and when did anyone last talk to you about magnesium? That is one question, by the way. They are the same question."

Ten years I have mentioned my sleep at checkups. Ten years of "cut screens before bed" and once, memorably, "have you tried being less stressed?" Nobody had ever connected the three things she just braided together in one sentence.

The notepad

She explained while writing. The body runs its wind-down on a mineral. Coffee burns through it. Stress burns through it. Past fifty the body holds less of it. When it runs low, the switch that should flip at 10pm does not flip, and no tea, no app, no ocean can flip it for you.

Then she tore off the page and handed it to me. Two words: "bisglycinate, nightly." And one sentence I have repeated at every dinner party since: "The oxide form in most American bottles is not absorbed. It is a very profitable placebo."

What happened when I got home

I did exactly what the notepad said. Found the bisglycinate form, in a sugar-free gummy, no melatonin because I wanted my mornings back, not a new fog. The brand I landed on is Kaive: 400mg, two raspberry gummies, third-party tested, which mattered to me after the placebo comment.

Week one, small changes. Week three, I stopped seeing 3am. My sister and I have already booked the Mediterranean for next spring. I intend to sleep through the ocean this time, and let it rock somebody else.

The math I did at the rail

The cruise cost us about $340 a night. That is what a bad night costs somewhere, even at home, in a currency you feel the next day. Thirty nights of the experiment costs a fraction of one of them, and there is a full money-back guarantee if your nights do not change. The notepad advice is the cheapest thing I brought home from Alaska, and the only thing I still use.

Helen S.An Austrian doctor told my husband nearly the same thing in Vienna. What do they teach over there that ours skip?

Diane K."Have you tried being less stressed" made me laugh out loud because I got that exact sentence in 2019.
