My CDE told me to eat this before sleep to help stop or control DP and it has worked a few times for me as well as stopped night time/sleeping lows although it isn't consistent depending on what else is going on:
1 T flaxseed boiled or put in boiling water for a few minutes, add some fat like peanut butter- I add heavy cream or almond milk instead because pb would prolly spike me. I also add 1 T chia seeds. It really fills you up. I cook them in about 1 cup boiling water or so added in to them. They are low carb and metabolize very slowly which can trick your liver into not releasing so much glycogen in the early am.
