Insomnia

Insomnia has been frequent this semester. For example, last night I fell asleep at 4 am and then woke up at 8:30. I didn't rest during the day and it's now midnight and I'm still awake. It hasn't even been that noticeable to me that I've only had four hours of sleep. So, maybe it's not insomnia. Truth is I usually find myself lying awake excited about hobby interests and time off this summer.
