Gang,
Since starting on insulin, I've been using 12 mm needle tips for my insulin pen, at the suggestion of my druggist and diabetes nurse.
Recently the druggist been having trouble getting the 12 mm needle tips, and I'm wondering whether I should switch to 8 mm, which are far easier to get. She did suggest I might have different results from my insulin because it's going in to a different depth.
Anyone have any experience with this?
