I have taken CO-Q10 for a period of 6 months several years ago. It is bit on the expensive side, as far supplements goes. I used to take it to help me stay alert. I didn't see any difference in my general alert level. I kept on taking it because I was under the impression it might take me longer than couple of months to see any improvements. I increased dose, changed brand; nothing happened. Currently I am only taking Fish Oil (Omega 3&5) and St. John's Wort. Both helps me with my anxiety and sleep. I used to stay awake for 24-36 hours at a time quite often with 12-16 hours sleep in between. Relied heavily on caffeine and my anxiety was off the roof. I completely stopped caffeine from my diet. Drink decaf. Tea. Exercise first thing in the morning to burn up most of my energy so that I get tired by the end of day and help me sleep. I still end up staying awake for ~20hrs a day, which is closer to my goal of ~16hrs and better than previous habit of staying awake for ~30hrs. If you have problem sleeping, kill the caffeine and it will solve half of your problems.
