Adult ADD medications

I am a healthy 37 year old male and recently diagnosed with ADD. We have tried Ritalin, Focalin XR and Adderall XR and none seem to me doing anything for me. Any thoughts? I am more aware of my ADD simply because I have learned a lot more about it and came to the realization of having to accept having it, but I am not sure the meds any doing anything for me. Maybe they are, and that's why I am here in the first place..... but i am not sure.... Help>>>>
