Synopsis
SG-1 is caught and sent away as slave labor, except for Dr. Daniel Jackson who is starting to overuse a Sarcophagus and suffers its adverse effects which are similar to that of drug addiction. When SG-1 is finally freed, they take Jackson back to prevent him from using again.
Upon their return to Earth, Jackson is found to be biologically unstable, apparently because of the somewhat narcotic properties of the sarcophagus. He goes through withdrawal, during which he is mentally unstable. He demands to go back to Shyla's world, saying that they are killing him by keeping him away from the sarcophagus. He attempts to escape, and eventually pulls a gun on Colonel Jack O'Neill, before breaking down and agreeing to remain on Earth and break the addiction.
