Force euphoria was a state in which an individual could enter after drawing on the Force so heavily that their cells were overloaded with energy. A symptom of Force euphoria was a rapid and excited voice. When the user's body became unable to keep him or her from collasping any longer, the euphoria itself was followed by a crash every bit as severe as that of a spice-addict coming down from an overdose. When Jaina Solo kept drawing on the Force to keep fighting during a battle to retake the New Jedi Temple from the Lost Tribe of Sith, she experienced this state, as did Vestara Khai when she drew on the Font of Power's dark energy to attack Abeloth.
