My name is Bob, and I have had ADHD as long as I have lived. I have taken Ritalin for most of my life, but my doctor recently switched my to Vyvanse. Because I had some Ritalin left, I tried it at the same time as the Vyvanse. It worked perfectly. The problem is that the DEA are quite strict, and they don't think that is cool, apparently. Some doctors, however, are fine with writing prescriptions for two ADHD drugs; I just have to find out who they are.
