Needle phobias, crash diets & drug tests (feat. Dr Hazel Wallace)
Our special guest this week is the Food Medic, aka Dr Hazel Wallace, who answers a listener's question about cutting out sugar - and analyses Alex's pre-Love Island crash diet. Also on the show we discuss how to overcome a fear of needles, how long cannabis can last in the body, and why people's hands go white when it's cold.
