Pretty sure I gave myself a panic attack this morning.  Jittery, nauseous, a bit cold, mostly my hands and feet, most likely clammy and light-headed/dizziness, and my heart was racing.  I also had 2 cups of coffee this morning, when I normally only have 1, and hadn't had any since Friday morning.  Caffeine jacks me up, not sure why I had 2 cups.  It was like pounded a 2 liter of mountain dew.  I was pacing around looking for something to do when I'm supposed to be sitting here WHF.  Gave the dog a bath and made some lunch.  Feel better now, a bit jittery still but overall a lot better.  Probably take a hot shower in a bit.
