There's an element of strangeness in it: being half in love with something for as long as one can remember and then, one day realizing one doesn't like it anymore. This was the case with my (erstwhile) addiction to coffee and sadness. One morning, I woke up, fixed myself my usual cups of caffeine and gloom and, after a few sips, decided I wanted no more of both.
I poured them into the drain, turned the water on, pelted the sink with disinfectant, and scrubbed with more force than usual.
I went out to buy some tea and bask in the sunlight.
