How vigorous is said exercise? I go through this exact same pattern if I don't get enough exercise. If I do 60-90 minutes of treadmill/elliptical/rowing in the morning then I sleep like a baby for 7-8 hours and wake up feeling fresh. On the other hand if I do less than 30 minutes of cardio or skip the gym on a given morning I start regressing into the pattern you describe. Compared to other healthier-living choices I can make (healthier eating, less drinking, etc), exercise seems to provide by far the most consistent and tangible results. Best of luck, I hope you figure out something that works.
