I know you mean well, but managing this sort of thing is something that's extremely different from person to person, very hard to get right, and often a source of great personal pain for people trying and failing. Please refrain or be extremely cautious about enthusiastically telling everyone what worked for your relative.

While I agree it's worth being cautious about how you phrase any "advice", I think the parent post was perfectly reasonable. There was something that worked well for someone he knew, and he mentioned it in case it might help.

For context, I've been a Type 1 diabetic since around '85 and, as I get older, I'm becoming more insulin resistant (Type 2) also. While I've been able to keep my blood sugar mostly under control, I test my blood 4-10 times a day and sometimes need to take insulin 5+ times in a single day (sometimes it just doesn't "work" and I need to take more in smaller amounts to bring my blood sugar down. I can't just retake the original amount in case the first shot suddenly "kicks in").
