I had an interview in Seattle in Dec. I did not particularly care, because I did not want to move to Seattle, but I thought that I could fly back and forth and ask for some remote work, etc. At any rate, it was not an interview I thought I would be anxious about. At all - because I did not want the job so much.

I flew to Seattle the night before and... did not sleep at all. Never fell asleep for a second. Just stayed awake in bed all night long. Not worrying, no, but awake. And I could not figure out why, because there was no jet lag - Seattle and San Francisco are on the same coast!!

I lost the interview, which was OK because I did not care, but asked the pdoc why I did not sleep (having taken my usual sleep medicine). She said that it was anxiety. So still anxiety... without actively worrying - still anxiety.

the word you used - "ingest" - is what I was looking for. Because in that state, you do not "eat" - you are trying to swallow and ingest, to no avail.
