While getting the recommended 8 hours of sleep is important, with ADD/ADHD developing a regularly sleep schedule is paramount. It is a typical habit for those with ADD/ADHD to stay up late. Like with most of the population, this occurs mainly on the weekends, which means that come Monday, you will have a difficult time waking up and this sets the tone for the remainder of the week. Make it a lifestyle change to get to sleep at the same time every day, including weekends and on vacation, and you will see your quality of life improve.
