Minimizing sleep

[toasterwater]

I regard sleep as a waste of time. I hate sleeping, especially if i sleep excessive amounts. For instance, today i woke up at 730, which was fine- i went to sleep around midnight the night before, so i was happy with 7.5 hours of sleep. However, I became tired as the day progressed (probably due to the sedentary nature of reading and conducting business online), and around 1pm i laid down on my bed and fell asleep. I slept for about 3.5 hours. This is 3.5 hours of potentially productive time that i cannot get back. The plans that i had for the day arent completely lost, but nontheless, this was a complete waste of time. I have undergone several lifestyle changes lately to try to minimize my sleeping habits. I became a vegetarian about 6 weeks ago with the hopes that it would increase my energy levels throughout the day and prevent those most despised "afternoon naps". Along with this I changed my sleeping schedule. I now wake up at 4am every weekday (work doesnt start until 5:45am or 7am) and i tend to go to sleep between 9pm and 11pm following the when-im-tired rule. I cannot follow this schedule on the weekends, however. I have to be awake between 11:30pm and midnight on Friday and Saturday nights. Because of this I have chosen to adapt my weekend schedule to go to sleep after midnight, and wake up around 730am. I currently excersize 3 times a week.
It seems that with a healthy, vegetarian diet; a refined sleep schedule; and a decent physical exercise regimen, i should be able to snub this little sleeping problem. Unfortunately, i still find myself becoming fatigued during sedentary activities (reading, online activities, etc.) and every once in a while I lose the battle and take a nap.
I am willing to try any reasonable suggestion if it leads to the correction of this problem. Sleep is the enemy- today i lost a battle, but the war is far from over...
