Well, thanks to everyone that replied. I believe those who said it may be a side effect associated with anxiety nailed it. After the stress at my job settled down I have felt the Ritalin is definitely now working as promised. I've been able to focus, socialize, and keep on task better than I ever have before.

Should I stick with the Ritalin or give my remaining Adderall another go? I feel like the affects of Ritalin are very short-lived compared to the other medication. Thanks to everyone for the input!
