Hi Tony,
US Marine, eh? Well, that explains why you don't get enough sleep
Yes, that is another way to induce lucidity ... just "notice" yourself drifting off and try to keep awareness when you enter the dream-state. It might be more pleasant when you have some R&R time, perhaps over the holiday break. Keep trying, though, with a relaxed intention.
Keep us informed of your progress, and happy Arabic studies!
