We’re giving you a peak behind the curtain as we share our first ever pilot episode of No Appointment Necessary, and it’s very fitting if you're doing Dry January. Join Cherry Healey and Dr Amir Khan as they take a look at alcohol. What it actually does to your body, your brain, and your hormones. Find out why women get drunk faster than men (and how your menstrual cycle, perimenopause and menopause change everything), plus why alcohol is technically a poison, why there’s no truly “safe” level of drinking, and how “wine o’clock” culture has shaped our relationship with booze. You’ll also learn why some people never get hangovers, what alcohol dependency really looks like, how to spot warning signs early, and practical ways to cut back without missing out.
