One of my first posts I made was about effects of an energy drink. It caused me to stay up all night. My doctor says it's not the caffeine to worry about, but the lack of sleep.

Lately, I've been staying up past 12pm and waking up between 9am and 11am. I am also 19. This is normal for a teenager, but I use to sleep waayyy too much because of the meds: going to bed at 9pm, sleeping in late, then taking one or two naps during the day. My meds have been reduced and I am much more energetic.

I've always been a night owl, so I'm used to staying up late. But what does my doctor mean about a lack of sleep causing mania? Is he talking about staying up too late or literally staying up all night?
