I also take both of those meds, & sometimes I feel a little more hyper than usual. I don't have racing thoughts but I can't stay focused on one thing for very long, & I have a lot of energy. I feel like I'm going to jump out of my skin if I have to continue sitting in one spot. Thankfully it never lasts that long, but I don't know what causes it. I don't think it's the medication, though.
