My brain went on vacation after carnival

I'm Brazilian and carnival holiday was last week. 4 days off. I back to work last Thursday but my brain didn't. Even with medication and coffee (not much coffee so I don't get too anxious). I work with import/export, and part of my job demands me to be extremely careful and look to any little detail, because one wrong info or a missing document can cost A LOT. But it seems my brain simply didn't came back from carnival with me. And I'm getting very pissed of with that. Any tip on how to hunt my brain and put it to work again? (I'm stopping to take escitalopram, I think it has some influence too)
