Sleepless nights

Nearly a month in Vienna.
Sleepless nights over the last week. Why?
Not that difficult to understand why. One key reason is that my intellectual mind got inspired and excited by the conversations I had with supervisor. Every time we talked to each other or they gave me feedback on my works, or even I picked up their words from my recolllection, I couldn't stop thinking - more precisely couldn't turn off my intellectual machinery, no matter how tired I was or how hard I tried to close my eyes. So many ideas flowing around and so much I want to share, sometimes to an extent that I really try to talk to myself!
This means I am passionate, and this is the very character any successful academic must have.
I need to sleep. I need something to cool me down. I need a way out.
But who can stop me? Someone said: 'if you are good enough, no one can stop you'. Perhaps not even himself! The only one who can is perhaps his partner and family. I used to ..... ok, it's gone.
well... my head is big enough, please bring me to somewhere relaxing.
