Nah, this is working

splashing with cold water wouldn't do it - it's deeper than that.. you'd have to actually hold your face in a sink filled with icewater for like 10 minutes.
My technique is working great though, and I'm sure it'll get easier the more I do it.
The main thing keeping me out of the water has been the combination of wind and low temps - which spell frostbite where I dive.
