Hey there,
Have you ever had lactose intolerance issues before? It
could be the ice cream, that as a diabetic, you shouldn't eat anyway right??
I'm a type 2 dibetic also, oral med and diet controled.(sort of..... I eat stuff I'm not supposed to too

)
I take
Actos and Metformin. It seems to be the Metformin for me
and a few other people I know who are taking it that is behind the
EWWWW factor,(no pun intended,however without even trying it is a little funny).
Do you happen to take Metformin?
If not, I'd try and give up the dairy for a few days and see if that helps.
Feel better, becca
