It's one of the most definite effects of strenuous exertion, either physical or mental. The exhaustion is real, accompanied by increased pulse and breathing rate, but distinguished from the ordinary kind by its quick onset, and equally quick disappearance within minutes after you move up the next scheduled dose of levodopa. I've also found that taking the extra dose beforehand will prevent the sudden collapse, as long as you don't overdo it. When you use up the supplemental (from medication) dopamine supply in your system, it may take several days to recover. Cheers, Joe J. R.
