When I eat radish it feels like I am getting a fix. I've never tried drugs but I imagine it's what it would feel like to be desperate for it, and how amazing it feels when you get it.
It takes me by surprise every time I eat radish! It only happens with the first radish, not subsequent ones in the same sitting.
Other things that feel similar - getting a good whiff of strong smelling petrol, and the first sip of sparkling water, when it hits your thirsty taste buds.
Am I weird??
