this is interesting, lots of people here don't like it/are disgusted of it!
i drink coffee, maybe one or even two cups at the morning and that's usually it. maybe another one in the evening if somebody from my family offers to make one.
i like it v much. i always drink my coffee black. i definitely understand those who don't like it.
I don't like it, stains your teeth and gives me anxiety
one night i actually drank 3 coffee cups in a row, jesus christ that was the worst. my heart was beating SO FAST and i was really anxious. i was pretty much in panic and thinking "oh my god i'm going to die!!!"
also on top of that i'm adding Verne's comment: it makes your metabolism faster so WELP chances are that you're going to have a sudden urge to SHIT after a cup or two. perhaps due to this it also dry your throat -> more mucilage which is not a good thing for singer.
...i've been meaning to reduce or drop my coffee drinking habit!!
