Hi Guys
Seems too be a few suffers out there... I have gone to using a good set of noise cancelling head phones, works wonders for fatigue and stress in a turbprop, and after a long day you dont take that buzzing with you...... also taken to avoiding the "louder" places for beers apre-flight...... but the simplest one bar far is the dreaded Caffine... try cutting out the tea, coffee, cola and cocoa at blighty for a week.....
but then again dont know anything better than tinitus to mask the bloody cricket chirping away at night....
