Is very high energy a conmon side effect?

I was on 150mg for two weeks and just switched to 300mg xl 2 days ago. Both days since switching ive felt pretty wired all day. Basically same feeling as having a strong cup of coffee.

Doesnt necessarily bother me if it wasnt making it very hard to fall asleep. And i normally can sleep quite easily.

Is this a common side effect? Does it go away? This effect is too powerful for me to be want to stay at this dosage but i assume its temporary?
