not sure if this was supposed to go in the diet section, but anyways.

Can anyone tell me the true importance of drinking enough water (and the effects of not drinking enough) and the effects of sleep on recovery (but mainly the detrimental effects of not sleeping)

I find myself dehydrated some of the times and i have a mild case of insomnia which ive had for around 6 years. i don't usually sleep till around 3am most nights... I'm seeing a chinese medicine place, getting herbs and acupuncture... not sure if it'll work.
