@kamikat Eh...depends. If there's something enjoyable about the end of the meeting, then maybe! Sometimes, I like to make something up for myself as a sort of "treat" for getting something done.
Maybe you can treat yourself to a more interesting activity afterwards and looking forward to that, will let the meds have something to attach to, to make you want to finish the meeting.
Everyone's brains work differently though. This is how my brain seems to work, so I treat it accordingly. It might not work for you.
