For mental health issues, often times a singular solution is not viable for everyone. For some, just medication might suffice (for that matter it may take a while to find the right medication). Others coaching and training. And for some combinations of the two may be effective. ADD can be a bit tricky given the nature of the disorder. In my psychology studies though, I found myself to take rather humanistic approaches and firmly believe that with the right motivation and guidance, most things can be overcome without medication. I suggest exploring your options. It's not a scam, it just may or may not be the right solution for you.
