That's what's going on with me today. I'm wired as though I'd had a handful of amphetamines.
In addition to being wound up, I'm getting some significant vertigo - not quite to the point where I need to hold on to something to stay standing, but not far off. I checked my pulse, and it's up at almost 100 bpm - normal is 60 bpm for me. I don't want to know what my blood pressure is right now.
Eventually, this is going to wear off and I am going to crash, but for now? ZOOOM.
Now to go see if I can concentrate enough to get some resume writing done.
