Over the past year, my hypoglycemic symptoms have declined significantly and I am now somewhat unable to detect low blood sugar levels.  I'll sometimes feel completely fine with a BSL of 50.  I realize that the length of time I've had diabetes (~17 years) and tighter control causes the desensitization to symptoms, but has anyone else experienced this or have any recommendations for reversing the problem?
The ice climbing season in Colorado this year was somewhat weak, but I still got out a couple of times.

I had an opportunity to go ice climbing in Ouray, Colorado in February.  I hope you enjoy.

I had an opportunity to go ice climbing in Cody, Wyoming back in January.  Hope you enjoy
