Well, energy drinks don't have that high a caffeine content compared to coffee -- a can of Rockstar has about 160 mg in it, which is comparable to a strong cup of coffee, but it's got somewhere around twice the volume. Red Bull is more like 80mg. So if your office coffee isn't scratching your itch, you're probably craving something other than caffeine, maybe even just sugar. I'd recommend experimenting with that a bit.

This issue isn't sugar, because I drink sugar-free energy drinks. On reflection, perceived weakness of office coffee may be in my head / based on my first couple poorly-made cups. So I may just switch back to that.
