What Drives Me Nuts Today

My heart palpitations drive me nuts. Apparently they're nothing to actually worry about but it's really really freakin' annoying. Basically my heart rate goes up from about 77 to about 90 for about 40 minutes. And. It. Drives. Me. Nuts.
Otherwise everything is normal.
So yeah, I try deep breathing. I've already tried all sorts of things like Xanax (which basically puts me to sleep). Even exercise doesn't really do anything for me.
And the most annoying time is when I'm trying to go to sleep. Because invariably my heart is all like "Hey let's GO!" at about midnight.
I can't wait 'till we get those nanobot-constructed replacement Special Forces bodies which last for 300 years before they need to be replaced. I'm going to get me TWO of 'em.
