“An hour in the tank and I’d come out relaxed, rested, my back feeling amazing, and in good shape to interact with normal, non-restaurant people. Interestingly, I found that for a day or two after floating, my experience of colours and flavours would be much more acute and intense. Reds were redder, blues brighter, and the taste of food more explosive. Lying in the tank, I’d feel like I was moving through space, my brain speaking to itself in an unfamiliar language.”
