Why am i randomly waking up 2-3 times in the middle of the night (please read details)?

This may be within normal limits, but many times when people awaken during the night, it's because they have low blood sugar,or hypoglycemia. See if eating adequate protein along with some carbohydrate at dinner, will take you through the night. Try this for five straight days. If it does not, you might try looking up and perhaps purchasing some Melatonin. Again, try it for five straight days. Best wishes.
