Impossible indeed! She's a miracle worker!
Halle Berry is claiming she has managed to wean herself off of insulin and drop from Type 1 diabeties, to Type 2. The trouble with this claim is that it's impossible to do.
Type 1 Diabeties means your pancreas is not able to ever recover to normal again. Type 1 Diabetics will be insulin-dependant for the rest of their lives.
Type 2 Diabeties is something you can recover from because your pancreas is able to heal and wean from insulin. If you're able to wean from insulin, you've always had Type 2.
Halle, Halle, Halle. Just keep your mouth shut for a little while. Clearly you have what we've all had: Pregnant Brain. Go find your tweezers, sweetheart.
