I like to read fiction late at night (after my SO goes to bed) on my Ikea Poäng, under a floor lamp, with soft instrumental music on the background (Chet Baker usually works the magic even when singing). Some days when I am in the mood I sip a finger of single malt, neat. I am a smoker but do not do it at home, so I vape whatever tastes like buttered coffee.
Setting this up in my not so big room is kind of my "wind down" ritual.
But if I am reading non fiction, I am usually on my computer with DEVONThink helping me with annotations and so on, but then there is no music, no whiskey, no vaping and no nonsense :P
