Sometimes when I'm in the ZZ, my most creative ideas appear. I've learned to force myself to jot down bits and pieces because I know that after the fog lifts, I'm not going to remember a thing. There are days when I actually do not remember the day or days before. My fiance finds this an extremely irritating affect because if we have been arguing, the following day I will honestly have no recollection of the previous day's argument. It is NOT that I don't remember, what it IS is that as far as my mind is concerned, such an argument never happened in the first place.
Memory recall is zip.
Other times I can remember very detailed events that occurred as far back as when I was 3 years old. Needless to say, this makes holding a stable job pretty much a no brainer. I still have those qualities, they just don't last as long. Again, a no brainer for that executive position. We are not ignorant, we are not stupid, we are not insane.
