During a recent run, due to low blood sugar, I developed double vision. Otherwise, I felt great. Out of prudence, I quit and decided to walk home. I had eaten nothing for 14 hours before the run, so I am sure the problem was low blood sugar.
The double vision started half way through a 6-mile run. Had I continued on with the annoying double vision, what might have realistically happened? I am in seriously good shape, so what realistically might have happened? What would have been the next symptoms?
