I sort of did the same thing and occasionally get the same feeling.
I committed to lifting weights 3 times a week though (in the morning), as a way to keep myself going as it makes me get out of the door and I come home refreshed, ready to get to work.
Other than that, eat healthy, get proper sleep, and meet people!
I'm curious what others think about #3 (The vertical scrollbar). Traditionally it's considered messing with the defaults of the browser, and wasting precious screen space; but I hear from more and more (graphical) designers that they'd like me to stop the page from jumping by doing exactly this.
To make a general statement like that based on a study purely on USA, seems wrong.
I used to live in Denmark where they (according studies I won't bother digging up now) have both the happiest people on the planet AND pay the highest percentage in tax.
