It doesn't really sound like OCD as much as it does OCD tendancies (meaning that it's sorta part of your personality but it really isn't the disorder). I have those, and I just feel like it's better if I make things even (so I do the same thing...if I twitch my thigh, I'll do the same to the other one)
Although, I don't have the disorder. It's really no big deal and you don't need any pills for it!
This is a COMMON misconseption...I'm gonna have to edit the sticky in this forum
