MOD formula for time log and number of fixed breaks

I have a sleep log where will need to put in time go to sleep, number of times up and such. Format will be something like this:

Time get ready for Bed (will be say 11:30 pm)

Time lights turned off (something like 11:40 pm)

How long did it take to fall asleep (will be number of times)

Did you knowingly wake during the night. (yes or no)

# of times wake during night (number of times)

In total how long did these awakings last last (will be fixed time like 15 minutes)

What time did you wake? (time will be like 6:30 am)

What time get out of bed? (like 6:35 am)

How many hours did you sleep last night? (number)

I am thinking an MOD type formula might work but not certain how to create with all these factors. Any assistance would be appreciated.
