Are you able to identify if a certain happy feeling is triggered by your drinking coffee?

I don’t know about you, but coffee never does it for me. Sure, coffee makes me feel more stimulated mentally, but nowhere near happiness.

Maybe it’s just your brain being simulated too?

I found that when I used to drink a can of diet soda around mid-day it gave me an emotional lift. Coffee just makes me kind of jumpy so I rarely drink it but I imagine the principle is the same.

“Chronic caffeine intake has been shown to increase the receptors of serotonin (26–30% increase), GABA (65% increase), and acetylcholine (40–50%). This may contribute to the elevated mood and perceived increase in energy we feel after a coffee (which makes espresso a handy pre-workout drink).” Source

No. I drink less than half a cup of coffee in the morning. Any more than that I feel shaky, irritable, scatter brained, everything except happy.

I haven’t noticed optimism, but I do find it comforting (I drink a bit of good coffee mixed with lots of milk and a little bit of sugar), soothing, and a little bit stimulating.

If I don’t have any, I sometimes get some withdrawal symptoms (headache, fatigue, fog, grumpy).

It keeps me awake and alert at work, and keeps the boss pacified because he never caught me asleep. Otherwise, I have been drinking it for so many years, I don’t feel anything one way or another.
