Numerous Emails, Late Nights, No Sleep = Project Management?

The title says it all. After being named the Project Manager for my team's project, I have this odd drive to get things done, and make sure that my team stays on track. I want to do everything. The wheels are constantly turning in my head. I have all of these ideas, because the project is something that I understand and care about. I guess I can understand now, how certain people in the cohort could push so hard. I don't want to come of pushy towards my teammates, but I don't want to except the minimal either. I will continue to shoot out information, sent out emails, etc.  I don't want, what happened last project, to happen this project. I have a project plan in my back pocket to make sure that we are on track. Especially with my name being associated as "Project Manager." When I was first approached, I thought it was a set-up. None-the-less, I press on.
