Taking Concerta after RNY??

Hi All - I'm trying to find some answers on this, but having a hard time.  I've Googled and looked and looked.... I take Concerta for ADHD and it has really helped me focus on my work (well... not today...LOL).   I will be having the RNY done within the next 3 weeks (YIPPEE!) and I really need to get more information on if I can still take the Concerta post-op.  I'm curious where the Concerta absorbs in the body and how it will be affected by the bypass.    Yes,  I will ask my Dr., but I want to have information going in.  This is not common, so I don't want to assume that he has all the answers for this.  I need to be informed as well, since it is my body.  :-)   I did print out some very specific information to give to my surgeon in hopes that it makes sense to him,  but I want to understand it as well. The medications and vitamins they recommend were discovered by the deficiencies of post-op patients.   I don't want to be the patient that determines that Concerta should not be taken after a RNY.   I understand that many of you won't have answers to this, but if you do have any information,  please reply to this thread.  Thanks so much! Jill :-)
