Recently things got so bad that I have started to simply tell people "Hum, I can't (decide on this | solve this problem) in a meeting. If possible, can I give you the answer first thing tomorrow?"

Some powerful people insist on the meeting anyway, always with disastrous results. But it's enough to not distress myself trying to make it work.

And yes, it's mostly because I can't think during a meeting. Very often I have an answer as soon as the meeting finishes.
