Prior to getting ME I had really bad adrenal fatigue so I had to eat a small snack before bed so adrenaline rushes wouldn't wake me up. Something like a rice cake with almond butter or some vegetable soup. Now, since ME came on, literally to the day, I can't sleep even 4-5 hours unless I eat a TON before bed. I'm talking like a full sized meal. Protein, carbs, fat, vegetables, everything. If I don't I won't wake up with an adrenaline fish but ill wake up just a few hours later and just be awake. Like its time to go. It may be 2 in the morning. Sice the onset of ME the only way I can sleep through the night is if I eat a huge meal. And, I am continuously testing my adrenals and they are actually performing better now than they were prior to the ME so there has to be another reason.
