Hey there x. I've just joined & my name is Helen. I'm type one. I'm very overweight, size 20!, & I have noticed that it takes very long for my insulin to bring my sugar levels down, even in the morning when all I have is a strong black coffee. Is it possible that because I'm overweight & the needle is too short, the insulin I take is just getting into the fat in my body & not getting straight into my blood. If yes, that would mean I need longer needles?
