Weather; Aircraft; Human Factors; Procedure
I was hand flying the ILS to Runway 2 approach at COU.  Weather was turbulent with light to moderate chop; IMC conditions.  Approximately 2.5 miles beyond the final fix; YATGU; the aircraft went into a left bank; nose down attitude.  Corrections were applied and positive control was regained.  Declared a missed approach and requested the RNAV 2 approach.  Flew the approach without incident to a safe landing.  Learned two days later at the FBO that a King Air had landed before me reported weather difficulties on approach.  This information was not provided by the Tower and could have provided additional situational awareness before beginning the approach. [The information could have lead] to selecting a different approach or going to the alternate.  Going forward; I will query ATC for any abnormal weather reports at my destination.  I am going to get additional training on integrating the autopilot into my ILS approaches to reduce the workload.  Also; after a long duration flight in IMC (3.3 hours) I will drink a bottle of water 30-45 minutes out and eat an energy bar to insure I am at the top of my game.
PA-28 pilot reports momentarily losing control of his aircraft during a hand flown ILS approach in turbulent IMC.  A go-around is initiated and vectors to the RNAV approach the same runway are received to a successful landing.  Fatigue and lack of pertinent Pireps were cited as contributing factors.
