Interesting; as a non-diabetic, there are lots of (nice) things I don't eat regularly (pretty rarely in reality) for general health reasons. Hash browns aren't a particular thing for me, but they'd definitely be on my 'not regularly' list (deep fried, comparatively simple carbs, lots of salt, etc.)

Genuine question, not trying to 'gotcha': do you think your stubbornness in this regard was somehow accentuated by having T1D? Is this perhaps a recognised phenomenon amongst diabetics? (An old friend with T1D was similarly [maybe even more extremely] stubborn, being perhaps the most badly-behaved and impulsive of our friend group at that time.)
