I'm right around the 4 months mark.
Normally I don't pay much attention to "me" when I'm shaving, but Saturday I realized that I no longer considered the "guy in the mirror" as looking different. I've totally assimilated the bald style and cannot imagine reverting to hair.
Should have done it years ago because I think the look is so much more fun. (I use it every chance I can to get a cheap self-depracating laugh: "Why did the tall, good-lookin', bald guy cross the road ...?")
But I refuse to wish I'd done things differently in the past. Sometimes I'm just a little slow.
