Coping with all day meetings

For introverts, work meetings are exhausting. I happen to be a part of an industry where serious meetings occur on a daily basis. Meaning that, only four years out of college, I have meetingitis, which unfortunately has no cure, there can only be symptoms management. I've developed many coping mechanisms over the years. I do everything from take many coffee breaks, bathrooms breaks, and snack breaks to intensively daydreaming. As long as I can escape the meeting room, either physically or mentally, the mechanism is usually successful and I am able to survive the meeting. Thank God.
