Sleep... does anyone know?

May sound a daft question but I thought I would throw it out there anyway.

I can predict my BG rise/fall after meals during the daytime. I am wondering what happens when you eat immediately before going to bed - assuming that you fall to sleep straight away.

eg
if I eat a meal with say 20g carb during the daytime I know I will spike after about a 45mins/hour and then be back to base level after about 2 hours.

if I eat the same 20g immediately before going to bed will the same pattern occur or will the onset of sleep change that pattern - ie avoid the spike?/reduce/increase the length of time until the level reduces back to baseline.
 
I can think of two ways to find out.

One is to set an alarm, go to sleep as normal but then test when the alarm wakes you. If not back to baseline you could test again later, but you wouldn't have slept continuously, so instead you'd have to do similar the next night but set the alarm a bit later. But the next night your body may not react the same, part of the frustration of diabetes is the variations even if you try to do exactly the same food, activity and meds.

The other is to get a 72-hour continuous monitor and see what happens on 3 successive nights while you're asleep. But the sensors for these are really expensive so I doubt you'd be given one just for curiosity. If you were concerned about sleeping through hypos that would be a different matter.
 
Thank you very much for taking the time to reply.

I guess the only way to find out will be to try to run the kind of test you suggest. I had thought that might be the case but kind of hoped someone might be aware of some obscure study on this subject.
