Yeah, been there. Cushions under every seat now. Restaurants are getting tricky too. Almost brought my pillow last week. The standing desk at work helps though.
the site access changing with weight loss is something most people don't anticipate - the fat tissue that made certain injection sites comfortable and easy to reach also shifts as it reduces. switching pen types is one option; a shorter needle appropriate for lower body fat coverage is another adjustment worth considering as the body composition changes
the auto-injector cartridge reliability variance is the thing that keeps some people on manual syringes even when they prefer the auto format - the jam-and-restick cycle on a bad cartridge is more stressful than just completing the injection manually. keeping a manual backup for the occasions where the auto hesitates is worth the small overhead
Ah yes, that exact feeling! Going from barely being able to close the seatbelt, practically begging for an extender just to get it latched, to having so much extra length you can actually pull the slack tight! That was a massive non-scale win I still remember clearly!
