In 1985, Dr. Richard Wurtman reported several cases of seizures brought on by drinking too many diet drinks. The first case involved a woman with no previous seizure activity who developed seizures after drinking seven liters of NutraSweet-containing beverages per day.
In the second case, a woman 27 years old had a grand mal seizure after drinking 4 to 5 glasses of Crystal Light™ containing NutraSweet. This patient experienced twitching, trembling, jerking, and hyperventilation.
The last case was a 36-year-old male professor who drank one liter of ice tea sweetened with NutraSweet every day and developed grand mal seizures after several days. He had no previous history of seizures nor of aspartame consumption.” Dr. Richard Wurtmann
