Sure no problem.
I also suggest some strength training. Strength training activates the GLUT-4 receptors in muscle cells, which then makes those cells absorb glucose without requiring insulin.
For instance simply doing body weight squats every morning (increase by one/day until you reach say... 100/day, then add some weight (like a backpack with books) and start at 20 again. Shouldn't take too much time each day, but will have a big effect over time.
