I recently jumped from a job to studying (engineering) <---- hard summer course, so might be part of my question

I had a real low energy level back when i was a elevator constructor/service man. At the end i really did not like my profession, so... Well, yeah. I think my energy level represented that... i felt tired all the time, no matter how much i slept

Here's the thing: Im now studying, and i kinda feel like got the hours under control. Sleep at 11pm wake up at 6am. (I start one hour later, but im used to waking up at 6am, but now i just use the time to relax with breakfast, instead of eating in the car etc xD)
(I feel much better in general btw)
But tonight i drank some wine with my father and discussed way too long, haha :P

Long story short... 6 hours later im still feel awake :O

When in normal "mode", i kinda have a pretty low energy/sleep level. I have psoriasis (not heavy) so its normal for "us" to get more tired by ... whatever -stress etc.

So what keeps me less tired than i should be, at this point? Why am i not sleepy? :O

Thanks guys ^_^
