Your sugar might be dipping too low at might. I know it sounds counterintuitive, but try incorporating some sort of snack closer to bed that might keep your blood sugar more even throughout the night.
My spouse was fighting the exact same issue and it only got worse during GLP research, We ran every bit of data we had through several deep research AIs. Bloodwork, sleep trackers, smart scale, doc notes, supplements, sleep log notes, and her typical diet and sleep for the week. They all came to exactly what @Retazempic is suggesting. She tried the bedtime snack for two weeks and found she was getting much more consistent sleep.
For a little more detail as to the why and what, here is a snippet of the AI explanation:
A lot of people who wake up like clockwork between about 2–4 AM are actually running into a fuel problem, not an anxiety or “mind racing” problem.
When you sleep, your brain is still burning a lot of energy, mostly from blood sugar. Early in the night your liver has enough stored sugar (glycogen) to keep things steady. But toward the middle of the night, especially if:
• You’re eating light or low‑carb
• You’re on a GLP‑1 drug like Ozempic/Wegovy
• You’re smaller/leaner or in a caloric deficit
…your liver can start to run low on stored sugar.
Your body sees that as a mini fuel crisis. To fix it, it releases two key hormones:
• Cortisol – raises blood sugar by telling the liver to release more glucose
• Adrenaline – gives a quick “kick” to mobilize energy and keep blood pressure up
In this situation, cortisol and adrenaline aren’t there to make you anxious; they’re just trying to keep your brain fueled. But both hormones also wake the brain up.
So the chain looks like this:
1. Blood sugar drifts a bit low in the middle of the night.
2. Body releases cortisol and a shot of adrenaline to push sugar back up.
3. You naturally hit a lighter stage of sleep (we cycle every ~90 minutes).
4. That cortisol + adrenaline bump is just enough to flip you fully awake.
You may not feel full‑blown panic, but because adrenaline is involved you might notice things like:
• Feeling suddenly wide awake
• Slightly elevated heart rate or a sense of “wired but tired”
• Difficulty drifting back off even though you were sleepy before
That’s why things like:
• A small protein + fat snack before bed (e.g., Greek yogurt + nuts)
• Avoiding big sugar spikes right before bed
• Not over‑restricting calories in the evening
can sometimes reduce those 2–4 AM wake‑ups. You’re basically giving your body a steadier fuel supply so it doesn’t need to hit the cortisol + adrenaline alarm in the middle of the night.
