I cannot use my stomach right now. I used/abused it for 8 years. ( I hated changing my sites, so there were times that I didn't change it until day 5 or so.) I use an OmniPod pump, and I use the back side of my arms for sites now. I just go from right arm to left arm and rotate the pod... like this right arm/cannula up; left arm/cannula up; right arm/cannula down; left arm/cannula down. Then start back over. This is working for me right now until I can start using other places. I tried my back, but it seemed to want to pull away after sleeping on it, and I haven't tried my thigh because I never got good absorption with shots or standard pumps, so I just steer clear of it. (Not to mention I used to almost always rip out the site pulling my pants up when changing or using the restroom!)
I am not trying to be rude or graphic here, but when you list your rotation for your "butt", where is it exactly? Like on the curvature, the side, or on top right below the belt line? I was "blessed" with one unfortunately, so I'm sure I could get SOME absorption there, just haven't known where to put it!
