Having not enough sleep will surely get you into trouble later when your body requires of you to sleep and you do not because of certain circumstances that you cannot leave like deadlines or mere caprices like playing another game in Facebook at 2 AM. Not being able to give your body enough time to repair itself by sleeping enough, your future will surely suffer, one way or another. You may have strong focus and concentration despite the lack of sleep so your work production may not really suffer but did you know that habitual lack of sleep robs you off of life? Anyone could have lived longer if not for the bad sleep habits earlier in life.
Some take a hard time getting awake because of a sleeping disorder. This is not good because it will hamper work and it will also cause accidents especially when on the road, driving. It is no longer a hassle for the person with sleeping disorder alone but there are lots of others who will be affected as it will lead to a chain reaction. It is not a farfetched idea because it just happened recently and the driver had a bus filled with passengers when he drooped to sleep. Imagine the many lives affected. It could have been prevented by taking some non-addictive pills. You can actually buy provigil online. Not just anywhere. The site can show you where to buy it safely and be alert when you need to be, and avoid accidents due to unnecessary sleep moments.
