This happens to me often. It happens a lot in the morning when I am getting breakfast. I'll come into the kitchen and suddenly I'll realize I don't know what I'm doing there. It'll take a second or two for my brain to kick into gear and remember I am getting breakfast!
But I've had it happen while putting away groceries and other things to. My hand will stop mid-way to the bag and I'll be like, "what was I doing?"

omigod!! I have done this!!! perhaps more than I realize, because I only started noticing it recently once I got on strattera....once you are medicated, sometimes, you realize stuff you never realized before...but my little, sudden "out to lunch" moments only last for a like a split second, and then I realize I was in the middle of something...being in the middle of fitting a customer for a shoe (which is usually when this happened) you kinda have to "play it off" or else the customer would think I'm insane, but I do know what you're talking about.
edit: this may be a very stupid question.....but did it happen when you were bending over for some reason? this is when it happened to me, like when I am bending over to fit a shoe for a customer, and then I almost "blank out" for a split second....like maybe it has something to do with the blood rushing to my head....just wondering...
This reminds me of when I was really young, and I would be talking to my parents, and my mind would get stuck in mid sentence because I forgot what I wanted, and I would break into a stutter,..."hey mom, can i..um, can i,..um, can i..um, can i..um....." and my mom (or dad) would stop me and tell me to think about what I was asking, and then I would do this, and then it would come back to me...
weird.
Chocoholic...ALL THE TIME! One day I was at the main street our RV park driveway ends at, and I sat there for a good 3 minutes not knowing which way to turn, because I couldn't remember where I was planning on going?
GypsyWomyn38430.5111226852I hate when my brain freezes. It happened to me last week in a presentation. I don't remember exactly what happened because I can't remember, but, I do remember saying a bunch of big words that made no sense to me and I'm sure to anyone else in the room. I just started spouting off and someone intervened to save me from further embarrassment. I can't even tell you what I said. I just know that it didn't make sense.
And, at other times I get so compusive that I have to battle with myslef to stop doing or thinking whatever I'm doing or thinking in order to get something that I was supposed to for that day.
