If you could travel back in time by transfering your state of mind/memories to your former self, would you transfer your tiredness to him?

Let's suppose you can travel back in time by passing your state of mind/memories to your former self. You go back to your former self who has slept some hours ago, a day passes without sleeping and you travel back in time again, and you repeat this process dozens of times (presumably to try to change an event you dont want to happen) . Would your former self have the accumulated tiredness of dozens of days (needing to sleep) or since the body of your former self slept a few hours ago would you feel energetic without needing to sleep all the time?

The need for sleep is physiological, just like thirst or hunger. It has nothing to do with state of mind and memories. So it depends on what effort the brain does when it receives those memories and state of mind; if the process is arduous then the brain will need sleep; and in this case it will happen from the first time. P.S. No matter how many times the process is repeated, from the point of view of the past you it happens always for the first time...

This is a wonderful opportunity to give your science fiction story a bigger science than we currently possess. We have no minds that are independent of the bodies they are currently attached to, so we have no way of testing whether mental weariness is separate and distinct from physical weariness.
I have personally noticed that my mind slows down after 16-18 hours of concentration, but the timing of that slow down is suspiciously close to other symptoms of physical tiredness such as muscle tightening, yawning, and gradually increasing eyelid weight. I cannot empirically determine whether two simultaneous events are occurring (separate physical and mental tiring) or if it is a single event with multiple distinct symptoms.
Your time traveler has an opportunity to learn what we do not know. Does the mind tire separately from the body?
So choose whichever "truth" serves your story best and run with it.
