You posted in New Member Introductions, which is the forum for introducing yourself. Since you've got a question, I'm going to move it to the appropriate forum for you (Basic Drug Discussion).
In regards to your question, we need some more information. What is your tolerance to benzos (like Xanax/alprazolam) like? Do you like Xanax or Adderall on a regular basis?
You can safely take both the Xanax and the Adderall at the same time....or, and this is my recommendation - you could take the Xanax once the Adderall starts to wear off.
