I think it IS a sign of IR, that's what the others on this site have been telling me. The same thing happens to me after I eat...I fell so sleepy it's like I'm drugged and I usually HAVE to nap for at least 3 hours before it goes away.
I'm waiting for the results of my last blood test for hormone levels, but i'm not sure if i'm being tested for blood sugar or IR. if i'm not, you better believe i'm going to demand it from my doc! my dad also has type 2 diabeties and i want to get this thing under control right away!
