I am new to the site and hoping to gain some knowledge from you people. Today I was prescribed 10 mg Adderall XR for my ADHD diagnosis. Psychiatrist recommended taking 1 10 mg then another 10 mg if the first one doesn?t help. I ended up taking 8 through out a 6 hour period and nothing has changed. I feel the same. Still have trouble with reading comprehension,concentrating on certain tasks, following along with my wife?s conversations and basic daily activities. I was given the option of the XR or IR, I choose the XR for the simple reason that it lasts longer. But I hear and read that IR is the way to go. Any of you had experience with taking both XR and IR. How do you compare the 2. Thanks
