You should have tried to sleep more longer

I am confused with that statement.

When treating for cancer you take some powerful drugs that keep you up. You will to sleep through them. I hope that information helps a little.
Feel free to ask any, any question. It is important that you understand, and it is a Hugh area to understand. I am still trying to get my head around it all

Oh. I was thinking enough rest will be very important for cancer patient. I mean enough rest for the body helps the body

You are absolutely correct with the sleeping part. You have to sleep, it helps with the healing process.
Everyday I try and sleep, all day long. I wind up passing out for an hour or 10 minutes here and there..

I think you are gaining a good understanding. Nice.
