Headaches and Fatigue

I am still waiting to see if I get to officially join this BMB and while I'm in limbo I'm trying to behave like I am pregnant to give it the best chance if I am.

So, what do you do about headaches? I get headaches quite a bit - have since puberty. The only thing that helps is Excedrin - which, of course, has both aspirin and caffeine in it. Tylenol won't touch it. I'm pretty sure that aspirin is a big no-no and caffeine is frowned upon (at least in excess). The only other thing that works is sleep but I'm pretty sure my boss would frown on me napping at my desk.

Which leads me to my next question. I work full-time. I am not, and have never been, a morning person. This morning I have been drifting off mid-keystroke! I don't drink coffee so that's out. I have to be careful with my sugar intake because of a major family history of diabetes so I'm trying to avoid soda but might have to give in. Maybe iced tea? Not as much caffeine and sweetened only with lemon. What do you all do to combat the fatigue?

Thanks! Have a beautiful day!
