Narrative:

Autoplt was on but the autothrottles were off. The power was not set high enough and the airspeed slowed until we got a stall buffet. The captain recovered from the approach to stall; but we then got a secondary buffet. I took the aircraft and recovered from the stall. Autothrottles were rearmed and the rest of the flight was uneventful. Contributing factor: fatigue.
