I guess I'm lucky. When I get in the woods in the morning it's cold. The last week It's been in the 40's when I get to my stand. I avoid coffee at all cost because it shrinks the capilaries in my fingers and my fingers end up cold. I also don't want it on my breath.

Nope for me, crisp morning air dose the trick. Get me in a warm afternoon sun and it's a completely doffrent scenario.
