I can go about 8 days before it starts to itch too badly. If I force myself to wait, after about 3 weeks the itching stops. But that was all pre-SR. Now I can't wait to shave.

I shave daily because the whiskers are long enough to sound crisp when I shave them. I can see them after a night's sleep but just plain want to shave more now. I can get away with shaving every other day but like it so much now I shave every night. Guess once I'm almost guaranteed no cuts, I'll switch back to each morning instead.
