I've always had a few minor tics, last a couple days, like I'll have the urge to shake my head or twitch my nose or something, periodically, every once in a while, few times a day... Never anything major, and I figured it was pretty harmless and never thought much of it. Gets lost in the stimming anyway. Don't even know if you can call them tics, they're so seldom.
But recently I've been realizing how much more this has been happening. Now it's almost daily, rather than once-in-a-while, and it's more obvious now; sometimes when I'm thinking I'll randomly say a word aloud that's associated with what I'm thinking, like my brain just triggered it somehow and I didn't stop the impulse to say it out loud. It happens when I'm not paying attention, for the most part.
This is very weird because from what I know of tics, they tend to be much more obvious in childhood and fade off as you age, not the other way around. I doubt it'll ever be a problem--every few hours, more under stress, is just not a major issue. For that matter, I don't know whether they can be properly called tics, considering how seldom they happen. Just wonder, though, whether this has happened to anyone else.
