Ecstasy and agony.

"Tim Lawrence was a film stuntman, appearing in Braveheart and London's Burning. But at the age of 34 Tim was diagnosed with Parkinson's Disease - an illness usually associated with the elderly. Tim now spends much of his time either frozen and unable to move, or twitching uncontrollably. There is, however one thing that relieves Tim's symptoms, one that challenges the medical community. The trouble is it involves an illegal and dangerous street drug - Ecstasy. Horizon follows the story of how Tim's inadvertent discovery is brought to the attention of medical scientists, and is now being studied in the hope of producing a new treatment for Parkinson's Disease (PD)."-- Provided by BBC. https://www.bbc.co.uk/science/horizon/2000/ecstasyagony.shtml
