I've noticed lately (well, I don't notice until my wife points it out to me) that when relaxing at home I'll randomly subconsciously break out into song, or whistling, or humming. Like, I'll just be sitting there, watching baseball on television, surfing the internet, and my wife will nudge me "Hon, you're whistling again". When my attention is called to it, I realize what I'm doing and stop. I also remember doing the same thing when I lived with my parents and brothers when I was 18.
I'm 27, and I have Tourettes, with one vocal tic and (at least) five facial tics, (though my symptoms are usually not too severe (only three or four other people in the world know I have Tourettes (including my wife), so I must be doing a good job of hiding it); every few years I'll have a really bad flare-up (like last summer, when I was ticcing REALLY badly).
I also seem to fit the symptoms for AS, but more on the mild side of things.
I'm guessing it's related to Tourettes, but has anybody else dealt with this?
