Can I have a Time Machine? Please!

Today, if given a time machine, I’d say the following:
“I’d go back to last night and go to sleep again.
Then I’d wake up and go back to last night to sleep again.
Then I’d wake up and go back to last night and sleep again.
I’d do this until the end of time.”
To be clear, I’m being perfectly serious.
Time travel to see mysterious beasts of the past or the weird cultures of the future is all very well – but barely register against using the machine to get some sleep.
