Last night I had a 150 mile cross country drive. It was mostly on two lane roads through the dark, hilly, curvy roads of southern Indiana. 2 sprays 5mcg p100 2 sprays 5mcg p102. After a few minutes my night vision improved and my eye/hand/foot coordination was on automatic. The tunes on the radio seemed better too.
It is usually an ugly drive that I do not enjoy. Last night I was in the zone and loved it.
Yeah increased audio sensitivity is often reported with P102. I get it too, but If I wear too much it drives me crazy (overstimulation). 5 mcg is enough for me. I’m a big music fan so I guess my ears are already very much attuned to enjoying the details in quality music 
Don’t know what P100 brings to the table; never had the chance to test that one. What does it do for you solo?
So far on my experience with p 100 has been the ability to be aware of everything going on around me and process other information, but to maintain my focus on the primary task at hand. It kind of sorts external stimuli.
