I am T2 and preparing to start using insulin. Naturally I am doing all possible homework including reading Walsh, Bernstein, and everything else I can find on the subject (including these forums). But book learning won't tell you everything; nothing substitutes for real experience.
So my question today is about injection sites. Based on your experience, are some better than others? Do different ones produce more (or less) rapid effect? What other issues are there?
In fact: in general, what useful tricks (or "gotchas" to look out for) should I be alert to?
