I personally have suffered from severe ADHD since i was a child.. they had tried me on many different medications for it, which hadn't helped. However Adderall is by far the best medication that I have taken. My attention span has expanded, I am able to perform the tasks that I need to do without getting sidetracked and whatnot. Especially at work and school. Granted if you take it late in the day persay after 6:30-7ish at night, you'll have a really hard time falling asleep at night. It is deffinately an upper, but it does do wonders for many people. Talk to your doctor or pharmacist about it, they know more than what anyone else would know.
I am 45 years old and have recently been diagnosed with A.D.D. although I kind of suspected it for a long time.I have been taking Adderall XR for 5 months gradually increasing the dosage.I feel it has made a very positive difference.At first Ihad a dull headache and I felt like I had been drinking alot of caffeine.After the first week or so I just felt a calmness,being able to focus and not be distracted I dont anger as quickly.It has been a positive experience for me.I wish I had tried it sooner when I was in school.I think the most important thing about taking it is working with your Dr. and finding the best dosage for YOU.
