It's upsetting that coffee isn't tasting good to me anymore. I'm sure it's a temporary thing. It had better be. I think the defining factor is utility. I'm not drinking the coffee because I really want a coffee.
What I really want is a bit of a caffeine detox and a day in bed.
I'm drinking the coffee because I need it to stay awake.
I'm at work.
I'm at my job. It's an important distinction.
I'm not working.
When I do work, it will not be at my job. It will be writing.
Some studies suggest that caffeine is psycho-reactive. That if you ingest it as a stimulant, it acts as such, but if you view it as a relaxant, it will chill you out.
I think that's bollocks. My blood's boiling with the stuff. I'm still exhausted, but shakes keep me awake.
