I have noticed that my body rocks back and forth very very slightly. I was using my laptop and had my finger resting when I felt my finger moving back and forth barely noticeable by eye unless you were looking for it. I looked at my finger and I see it moving slightly back and forth and then noticed a very weird feeling of me rocking but barely noticeable. I uncrossed my legs and still felt like I was rocking. I am not leaning against something and not it is just my head rocking. What does this mean? I am currently on Lamotrigine 50 mg daily.
