When I first started insulin, which was recently, I used 10g/i.u. However, I now only use 4 g/i.u. If I feel the leaast bit hypo I just have a glass of juice. I'm not recommending a low dose of carbs post shot, that just seems to be what works for me. I do however end up feeling a little bit hypo about an hour and a half after the shot. If I take in the recommended 10 grams, or even as low as 7 grams, i dont feel hypo at all. By the way, the onset of hypoglycemia sucks, and you're better off safe than sorry with insulin.
