Soylent or other drink alternatives for Diabetics?

I don't eat breakfast. I usually have an energy drink or coffee and call it energy for my mornings. But I would like to actually have something semi nutritious that I dont have to cook like Soylent or some instant breakfast drink. Preferably something I can mix with my coffee.

Soylent has 84 carbs per serving. And there's 3 servings to a bottle! Are there any alternatives that aren't jam packed with carbs and have some decent amount of protein, vitamins, and other stuff I usually don't concern myself about?

Bonus points if 8 don't need to add milk and can use(or already has) soy or Almond milk.
