Where do you inject your levemir?

Where do you inject your levemir or lantus? i was told when first diagnosed to inject it in my legs and use other parts for the shortacting. was there a reason for this or anything?

I think the abdomen site is faster, legs etc. are slower unless you're walking around etc. I inject both levemir and novolog into my hips and thighs now only. The abdomen is too sensitive for me now and it works too quickly for me.

I inject lantus in my thighs sometimes butt. I never use my tummy or arms for Lantus as I use that for novolog and don't wanna use up my novolog spots.
