Sally, Nick, and Jane are good friends. Jane and Nick are regular users of the drug ecstasy. Sally has never tried this drug but feels pressured to give it a try. She is a bit nervous about its side effects and decides to do some web research. She discovers it is a synthetic, psychoactive drug chemically similar to the stimulant methamphetamine and known as MDMA (3-4 methylenedioxymethamphetamine). Sally also reads it is often linked to heat stroke and dehydration with recommendations to drink large quantities of fluids. Sally, Nick, and Jane attend a party on Saturday night. Sally decides to try ecstasy with the rest of the group. Sally, Nick, and Jane all consume their ecstasy pills after using their home testing kit to determine the ecstasy contains no hidden substances. Sally has been heeding the internet advisories to be aware of fluid intake. She has consumed a very large bottle of water already. She hasn't had to go to the bathroom and thinks she may need more water, so she starts on a second bottle. Jane and Nick are just eating potato chips by the handful on the couch, thinking about how silly and paranoid Sally is about her water drinking. About two hours after taking the pills, Sally starts complaining of being tired and having a headache. Despite the water Sally drank, she still feels thirsty. Nick and Jane are very alert and feel fine. Sally seems more and more disoriented.
