Milk is something like 5% low-GI sugars (lactose and galactose), so you're going to have to drink a lot of it to spike your blood glucose.
If you really do want to drink that much milk, and are worried about blood sugar, you should try lactose-free milk - it's just milk that has the enzyme lactase added to it, which breaks down the lactose to galactose, and also results in a bit less sugar overall (to something like 3.5%). I can't tell the difference, taste wise.
