I personally haven't had the type of sleeping issues you describe after not taking meds for a few days. Any sleeping issues I have are usually related to when I took my med's. There have been times that I was involved in a situation that was outside my normal routine that required a lot of focus and attention and I would adjust my med schedule to accommodate the situation I am in, which usually fell later in the day or early evening. Taking my med's late in the day or early evening really messed up my sleeping schedule, but that doesn't happen often. You might want to try this, try not taking med's on a single day 2 or three times during a month. Usually pick a day where you have nothing important going on that requires a lot of focus or attention. I usually pick one of my days off when I'm just doing my own thing, going for a hike, shopping ect. Doing that avoided running out before my next Dr. Appointment. From what you describe you do have ADD/ADHD, symptom's vary and each persons symptom's are unique. From what you describe about your behavior after taking med's tells me that you do have it. Because if you didn't you would be getting the "speed" like effect from stimulant ADD med's. As for the opinion from above from "NoId", Everybody DOES NOT HAVE ADD, everybody forgets, everybody gets distracted, everybody has trouble concentrating or focusing on occasion. The difference is that in the ADD person these are not just occasional issues, these are issues that occur numerous times a day to the point where it effects our quality of life. ADD is not something you view, it's something you experience, and everyone's ADD is different. This quote came from a well known Doctor ,who is ADD and writes books on the subject and specializes in treating it, he was trying to explain to a young kid who just got diagnosed what it's like to have ADD. He said " The brain of someone with ADD is like a Ferrari, very powerful, but has brakes that came off a bicycle. One of the issues with having ADD is actually accepting that you do. There is a lot of ignorance about ADD, usually that comes from people who don't have it. What you should do is educate yourself on it, the resources are endless. Most of the negative information about ADD come from people who don't have it or come from religious organizations such as Scientology which is very anti-psychiatry, anti-medication and anti-pharmaceutical industry. You also have people that are just anti-medication for their own personal reasons. You have med's that made a big difference so there is no reason for you to stop, however, med's are not the only thing in the treatment of ADD. But the key is to educate yourself, everyone's ADD effects them differently. I didn't get diagnosed until later in life, not much was known about ADD when I was a kid. Someone like me was always considered stupid, lazy, unmotivated, nut, the list goes on. After lots of medical research it was discovered that people with ADD/ADHD were "wired" differently, we processed information differently. When I got diagnosed I also was told that I had an extremely high IQ. I always knew I wasn't the person that people described, in fact I now realize that I am a lot more intelligent than the people that used to call me stupid. Try to avoid comments from people like NoID and others alike. There are several good ADD related pages on Facebook.
