In episode 5 the narrator recounts a tumultuous period after being misdiagnosed as Type 2, leading to chaotic personal decisions, career changes, and risky living. A GP finally recognizes diabetic ketoacidosis and diagnoses Type 1, starting insulin treatment.

The episode also covers career highs in financial sales, the 1990s property boom and crash, and how untreated high blood sugars affected judgement and relationships. It ends with the narrator heading to university while still adapting to life with Type 1 diabetes.

A candid episode tracing a young RAF steward's journey through basic and catering training, unexpected romances, married life, and a life-changing four-month posting to the Falkland Islands where he found unexpected success.

Returning home he leaves the service for a new career, is misdiagnosed as type 2 diabetic, and struggles with the early consequences of unmanaged type 1 diabetes — setting up the challenges to be explored in future episodes.

In episode three I reflect on my difficult early relationship with food at boarding school, the heavy smoking and drinking in college, and the cramped social life that left me underweight and unsettled. I describe working at the Grand Hotel, where long hours, late nights and drinking mixed with college life.

I also recount a distressing encounter with the deputy general manager that led me to resign, and how that pushed me to join the RAF. The episode closes with my tough basic training, an injury, and a hint of what comes next.
