Does coffee make you happy and alert, or just a jittery mess?

Jittery mess, but my one can of diet soda mid-day seems to do the happy and alert bit for me.

Caffeine used to make me jittery, but I’ve built up such a tolerance that it no longer even makes me feel alert.

Sometimes boost the mood but most times, makes my heart beat faster, gives me intestinal problems and makes me anxious. Still love the smell and taste and every time I say that I won’t be drinking any again, I end up getting another cup!

one cup and I am just jittery.more than one cup and I am a jittery mess.

I drink decaf, but sometimes if I am really stuck on a project a cup of caffeinated coffee boosts me through.

Happy & alert. 20oz max.

The more cups the better! It cheers me up and when I have a headache it stops after coffee!

All of the above. I need one cup in the morning and that makes me feel “normal” more than a couple of cups these days will make me jittery. I used to drink it all day long.

Kinda makes me sick at my stomach.

It gives me a boost to wake up and there is something comforting about the smell too!
