All of this describes what my blinking tics are like. Sometimes it's just plain blinking, sometimes I roll my eyes into my head, sometimes both at the same time. The eye rolling got me into a lot of trouble I didn't intend as a kid and doing both at the same time make me look like a complete zombie. When my emotions get intense (nervous, excited, or angry), it gets worse.
One Aspie I know personally has a blinking tic, but he tics less than I do. Anyone here should probably look into a tic disorder like Tourette's Syndrome. Could possibly be your solution.
