Like "I meant to post this earlier but I have been running errands all day. Ahh the joys of Thanksgiving. Anyways, it sound like we got our answer. Everyone is correct. According to my doc, you can inject either in the belly or the upper thigh. The upper thigh area doesn't lessen the strength of the insulin. She confirmed what Uncle Lew said, that it just moves slower through your system if you inject through the thigh. Other than that, it is the same hold count and release, as with the stomach. Happy Thanksgiving."
