When shaking my head or sudden head movements make the room spin temporarily or throw me off balance more than they should. When it'll be hard to get home or reach a quiet, safe, private place. I weigh the various factors and make my best guess. (5/5)

When my hearing is worse and mushier than usual. When the 24x7 tinnitus is louder than usual. When I'm bumping into corners and door frames as I try to walk through the house. (4/5)

Warning signs that lean toward canceling my plans include: When the outing will last more than a few hours because forecasting beyond that is iffier. When there's a long car ride involved because that can be a trigger if I'm in a marginal state. (3/5)

Another compelling indication is when I'm completely worn out from recent flare-ups. When the decision is less obvious, however, I have to weigh various factors and make a judgment call on whether I'll be better off staying home. (2/5)
