Sick days, shifting schedules, and the evil of caffeine

Here it is, 1:27am, and I am wide awake. I was feeling ill from the weekend and decided that it was in my best interest to lay low today - get some sleep, recuperate, and possibly get some much-needed school work out of the way. Well, mission accomplished, but perhaps a little too well. Now I am full of boundless energy and, well, it's time for sleep; thus begins the viscous cycle of inadequate sleep, unavoidable cat naps after work, and more sleepless nights.
Things would have been fine, but I decided to try an experiment a workmate told me about double-brewing teas to get the caffeine to steep out. I think I failed my first attempt, but it seemed to have a bit of an effect on potency; I felt fine for an hour or so, but then it kicked in with the usual level of effect. I guess I will have to ditch the teas I still have that aren't herbal, which is a shame because my mom bought me some really nice varieties for me last year. So, thanks for the advice, but I think my system is a little too sensitive for even that method!
So, now it's time to see if good old chamomile can put me in the right place to catch a few zzz's; nothing worse than a bleary-eyed bike commute in the morning!
