What are some things you can do in a hospital room for 2 weeks? How can I stay awake?

I've pretty much been appointed as my brothers watcher while he's in the hospital (If you want to know what happened look at my previous question) for about two weeks.

I'll be alone most of the time with him and hes probably going to either be asleep or not alert enough to do anything except try and pull out cords and his catheter (which he's been doing a lot) and say simple sentences (brain trauma patient).

He has to have 24/7 supervision so I can't leave the hospital and I'm being dropped off there anyways (my home is 4 hours away) so I don't have much of a choice.

My mom got irritated earlier when I told her I would just use my laptop, tablet and iphone and said I wasn't there to play around I was there to watch him but I'm going to bring my stuff anyways or else I'll just be staring at him 24/7 for two weeks with nothing else to do and she's not going to be there anyways so she doesn't really have a say in the matter.

What are some other things I can do though? I already have reading covered and I don't draw. My tablet, laptop covers anything electronic but eventually I'm going to lose charge on those things and I'll need something to do while they're charging.

I also need some ways to stay awake through the night. I usually go to bed around 2am but I won't be able to do that I'll have to stay awake through the entire night and I need some ways to keep me awake after repeated days of this (I'll have like short periods of time where I can sleep but they're going to be during the day).

Well, I would bring some puzzle book (physical; not online or computer-based), like words search, sudoku, etc.

I agree ^
Anything that'll keep your mind busy and when you need to think you can continue to be alert and watch him.

I bought my netbook to the hospital when i had surgery, i don't understand why you need to be there 24/7 when there's nurses all over the place.
