Hi,
Welcome to the forum, I Stroked in Feb 07, and I too, have noticed that I now have a VERY short fuse now, to what I refer to as "stupid people" People that don't use common sense, people that I feel should know what they are asking me, or know certain things. There are just certain things that annoy me all to hell, and the thing is, is that I work in IT, and deal with people all day long, I just vent after talking to the people, and move on, sometime I need to get up and go for a walk, and get away from my desk.
Driving................that's another place that I have REALLY noticed it, as well has my wife, other drivers really get to me now, you know the one's that get on a freeway at 15 MPH, drive in the fast lane at 30, etc. Just things that I used to just say "eh, whatever............."
Hang in there.
