eating and sleeping - connection?

Not a medication question really but i guess this goes here since its sort of related.
After i think two weeks without sleeping more than a couple of hours at once and only eating the odd bit of chocolate, i finally managed to have something healtheir last night then went to bed and slept like a log for 5 hours, best sleep i've had for a month or so. Now i'm wondering if they're more closely connected than i thought and breaking the downward spiral a little on one will help with the other. I did read something once about how deficincies in certain things makes you into an insomniac, because if we lived in caves and weren't eating enough it'd be because we needed to go out and procure some food - our bodies refuse to rest much without food so we wont just be tired from lack of food and go to bed and starve slowly. I've tried zopiclone tablets, which made me more wired up even the day i had 3, tried drinking which helped me go to sleep but i still woke up a couple of hours later, tried all those selfhelp things about quiet time and and writing before going to bed etc, and none made the slightest difference. So maybe its time to go back to the simplest solution thats staring me in the face and try having something warm and nutritional before going to bed for the night. Feel sick if i eat anything solid so i might make a big pot of lentil vege soup today and try drinking that right before bed instead of cocoa or water. Has to be better than eating a pile of chocolate before bed at least lol.

Anyway anyone else noticed whether their sleep is affected by their appetite and what helped change the cycle of it?

Magnesium is supposed to help with sleep - worked with me for a while before I started on Cypromol (cant remember how to spell it now - lol). Chocoate is a stimulant, like coffee and anything with a high sugar content.

Chocolate is also has caffeine content and it would contribute to keeping you awake.

If you are low on calcium and magnesium it can also cause sleep problems. It is highly likely that you are given you are expecting as when you are pregnant the baby absorbs a lot of your own calcium and magnesium levels for bone growth.

I have also trialed magnesium orate before bedtime with some success.
