I don't have any personal experiences to share, but I thought you might want to know (if you don't already) that Concerta and Focalin are related drugs. Concerta is methylphenadate, the same ingredient that is contained in Ritalin. It differs from Ritalin in how the pill is absorbed into the blood stream once it is swallowed. It is formulated in such a way as to be absorbed more gradually - it is an extended-release version of Ritalin. The methylphenadate molecule comes in two forms. Ritalin and Concerta contain both. Focalin, on the other hand, contains only one form of the molecule - the one that does the good work. It leaves out the form that might be producing the flat affect for your child. I really don't know for sure if this is the cause and effect that you are seeing, but that would be my first guess.
Hopefully, someone with more knowledge and experience will comment further.
