Narrative:
We took off from bna on runway 20 left in a heavy -800. Right after takeoff; we encountered light to moderate turbulence and moderate rain. At 1;000 feet I asked for flaps 1 and then flaps up as the aircraft was accelerating quickly through 195. Within seconds; the airspeed began to decrease rapidly and we were quickly in a 1;200 fpm descent. I reduced the angle of attack to approximately 10 to 12 degrees and added full thrust. At about the same time; we got the stick shaker for about a second. I put two hands on the yoke to get control of the aircraft and my first officer put his hands on the thrust levers. I reduced the angle of attack; the aircraft begin to accelerate quickly; and we continued our climb.possible preventative measures: we used the autothrottles on takeoff and at 1;000 feet the throttles began to come back as we were cleaning up the aircraft. In the future; if I encounter the same weather conditions; I will not use the autothrottles for takeoff.
