As someone blessed with severe combined type ADHD (aka super ADHD) and not entirely happy with my current medication, I'm always on the lookout for this type of news in a form that is relatively digestible.
The one thing I've been running into, is that all the medication works great in that they are all more or less successful in achieving those behavioural changes I am looking for, but none of them last anywhere near as long as advertised (normal release 10mg Ritalin effects come and go within the first 30 minutes of taking), which leads to nasty rebounds and such.
Currently I'm on 30+30+20 mg of staged release methylphenidate (Medikinet) and it whilst it does (barely) last me the day, there are other things that make it not so great (which I'll spare you the details of, unless interested). Just chugging along, waiting for something better to come along in the hopefully not too distant future :)
