Why wouldn't you have access to your car kit? You don't drive to work?
Normally I take the train. If I have access to my car kit the gear in my laptop bag and office drawer will be irrelevant, or extras for coworkers.
In winter I'd have a few chemical hand warmers in there.
Good idea.
I'd rather have extra glasses than contacts (especially if they are daily disposables).
I usually get 3-4 weeks out of a pair of disposable contacts. I have been looking for reader-style optical frames for spare glasses.
Ear plugs (your office mates may snore, etc.)
I carry these for work.
Blinders (so your office mates can have lights on if they want)
I find it easier to sleep with the lights on than with blinders.
Sore throat lozenges, Lipton Cup o' Noodles packets.
Lozenges are in the kitchen FAK, along with coffee, tea, hot cocoa and the like. Some instant soup is a GREAT idea.
I might have a pair of heavy wool socks for this. Deoderant should have been on my list.
Another excellent idea.
Also, I want to add a candle to help warm up the small conference room I'm eyeing as my temporary bedroom.
