I do not take it but perhaps I can give you a little insight into it

First, it is generally considered for high blood pressure. As an off label use (and I believe it is now an accepted use) has proven to be effective in treating inattentiveness without stimulents. Ritilin is a stimulent which comes with a whole set of issues particularly long term. This medication helps regulate norepinephrine.

Were you on an extended dose of Ritilin or were you taking it a few times a day? One of the great things about this medication, aside from not being a stimulent, is that it is extended release and often times can be taken once daily. Will not cause the insomnia associated with stimulents and does not usually have an effect on appitite.

Have you ever had any problems with high blood pressure? can be common when taking stimulents. Might be why he suggested this one?
