In this episode, Martin and JP discuss addiction with addiction specialist nurse, Pam Diamond, a seasoned mental health nurse with a privileged career dedicated to addiction and trauma, particularly within the military environment. Pam shares her unique insights from years working with the Royal Marines and other services, revealing the hidden struggles faced by high-performing individuals.
We explore:
The invisible battle: Why addiction, especially to alcohol, becomes a sneaky and often encouraged coping mechanism in demanding fields like the military.
Beyond alcohol: Pam sheds light on other prevalent but often hidden addictions she's encountered, including gambling, pornography, and even excessive gym use.
The changing landscape: How societal shifts, such as the rise of social media and increased health consciousness, are impacting traditional military drinking culture.
When health becomes harmful: Identifying the tipping point where a seemingly normal behaviour transforms into a destructive compulsion.
Breaking the silence: Practical advice for individuals recognising problematic patterns and for friends and family seeking to support those in denial.
The path to recovery: Understanding the challenges of overcoming addiction, the importance of seeking support, and remembering your "why."
Join us for a candid conversation that unpacks the complexities of addiction in high-stakes environments, offering hope and guidance for those grappling with these silent battles.
