Can you control your sleeping pattern and amend it ?

6-8 hours of sleep is the recommended time. I wouldn't suggest getting less than 6. I go on about 6-7 and I'm fine.

It is completely possible to adjust your sleep cycle. You don't need to slowly take off time. Just do it. Set your alarm for 6 or 7 hours later and wake up. You may be a little tired the first day, but after that you should be fine.

brilliant thanks. set the alarm tonight So you say that after first day or two my body will be fine but will my physical strength or endurance drop as a result of not as much time recouperating?

I have no idea. You may be tired for a day to two, that's all I can say. It won't drop permanently.

I think that you can mantain a sleeping pattern by going to sleep at the exact same time each night/day and waking up at the exact same time. The first day second day or week may be rough with your hours but you will get used to it. Im not exactly sure if you will be extremely tired or not. If so, then here are some tips.
- if your eyes feel heavy (put cold cold water on a paper towel hold it on your eyes for 2 mins. IT WAKES YOU UP! AND REDUCESTHE HEAVY FEELING
i wish the best for ya.

It is something that is defiently possible.
At current I get quite a lot of sleep however I've gone through stages of being awake for more than 100 hours, or getting around 2 or 3 a night.
It isn't ideal but it's doable.
As silly as it sounds the amount of sleep you get before midnight actually restores your body more, so if it's at all possible I suggest you go to bed early and wake up early
lol even if thats 11:30 instead of midnight.

Try to get blocks of sleep, 20 minutes during lunch, an hour in the afternoon and morning than night really wont do much for you ...get all your sleeping done at once.

Things like fruit wake you up and give you more energy than caffiene so in the mornings grab an apple over coffee.

Hope some of that is a little useful, oh and welcome

True. For actual restive sleep you have to go through the REM (dream) stage, That can take on average 30 minutes to reach, so anything less than that is just a "cat" nap that my physically restore you, but leave you mentally exhausted.
