Acronym
BBO — Bedazzled Badgers Orbit.
Story
A sleepy lighthouse keeps glowing through the whole night while the dinner fireworks are handled by someone else. The point is quiet background light, not a sudden flash.

- B (Bedazzled) → Background: Provides steady background insulin coverage between meals.
- B (Badgers) → Between-meals: Bridges fasting gaps when no meal is being eaten.
- O (Orbit) → Overnight: Covers insulin needs overnight rather than meal spikes.

Know the limits
Basal insulin still requires individualized use; it does not by itself address acute hyperglycemia or meal peaks.
