Coffee.

I should not underestimate the effect coffee has on my morning performance. I do this all the time when I don't have cash, because to get my fix, I need to walk down the street to Starbucks since the cafe in the building won't take a debit card. Cash only. Massively frustrating.

So I'll let this be a lesson. I shouldn't be surprised when I'm still sleepy when work rolls around if I never bothered to fix the situation. And coffee is excellent, so there is a sort of double incentive.
