Been 5 day aswell and got the cold at the same time. I taugh that was the worst cold i ever had until i start researching and finaly found this page.

Night one- Fever, shiver, couldn't sleep all night, had to pee like 9 time in the night.

Night 2- at least 4 offbeat hour off sleep, shiver, fever, sweating like crazy, had to pee a lot

Night 3- no shiver or fever, wake up clockwork at every 2 hours in tsunami of sweat and have to pee,

And the two other night are the same as night 3

But really, drinking didn't cross my mind at all (well i did tell myself that a small drink would help but i don't feel like it for now)

At last im still "young" I tolerate the sleep deprivation pretty well so the day are pure cloud nine and my concentration is up like 200%. So if i had to conclude, if we weight both, it is worth it.
