Low-level anxiety, procrastination, jittery energy useless for humdrum work, bad overall energy levels if you consume alot of strong coffee, painful wakeup in the morning, adrenalised brain geared to snap decisions rather than measured reasoning.

Or

Bounce out of bed at 100% energy, fluid easy reasoning, easier learning, relaxed, enjoy slow movies, good overall energy, fine with humdrum activities, far less procrastination. Less impatient with people.

The caffeine-energy thing is pretty bogus. The problem for me is that I find it fun.

Just realise that giving up caffine means tapering for many people as the migrained a heavy coffee drinker can get form cold-turkey can be the worst, worse than anything I;ve ever had before. Also, even decaf and cocoa have too much caffeine, and with the reduction in tolerance as you come down in dose, so you become more sensitive. You really have to give it up completely, which is a shame. But the upside is massive.
