When I say "2-4 weeks," I'm referring to hard withdrawal. Depression, not wanting to get out of bed, laying on the couch not communicating with the family, not eating, calling in sick to work, etc.

That's because she is still making contact. At this stage of the game, mood-wise, "BAD = GOOD and GOOD = BAD."
