Now I set my alarm for fifteen minutes before work. It's preferable for me if I go to bed early enough that I wake up with enough time for a shower, but if I don't I can take one after work (or during lunch). The only reason I need a whole fifteen minutes in the morning is that it takes a couple of minutes for me to log in my Mac and VPN in.

At work we have nice coffee machines with free coffee. I have coffee at home too but I am less tired in the morning. Not that costing a little prevents me from drinking coffee, it's more that it being free is an enticement to drinking it, as if I am missing one of my perks of the days at the office when I skip coffee. Also, I am getting less physical activity every week now, so I also avoid coffee for the calories, and go for water instead.

same mentality for me.

> so I also avoid coffee for the calories, and go for water instead.

i'm pretty sure coffee is like almost 0 calories as long as you dont add milk, isnt it?

By just drinking water/decaf coffee/decaf tea, and putting in an effort for a decent meal, I started getting more consistent energy levels. Your mileage may vary.
