Charles,

This poll has no meaning. Every head injury is different.

There is no way to compare injuries and outcomes. Even the experts know this. Some doctors may throw out general time frames but they have no basis in the individual's condition. They are just generalizations.

Have you tried sleeping in different positions, like in an adjustable bed or recliner? Inflammation in the neck can cause all sorts of problems. For me, it interrupts my breathing. It can cause blood pressure and heart beat changes.

My sleep is dependent on keeping my blood sugar up.

If you wake up about 7 hours after your last meal, you could be waking because your brain is needs energy.

You could try eating a complex carb and protein snack close to bed time. Or consume a glycemic oriented drink like Glucerna or Boost Glucose Control or the other brands.
