I was put on propranolol 10 mg yesterday because I get performance anxiety. I have a really important presentation tomorrow and I feel anxious not knowing the effects of this drug. I wish I was able to publicly speak or experiment with it way before tomorrow so I can know how well it will work and help with my performance anxiety. However, I do take Adderall, and I have a big concern here. I am very worried that Adderall would prevent propranolol from working. Adderall does increase heart rate, and Propranolol does the opposite. I don't know what to do. With Adderall, my heart rate doesn't really go up unless I am doing some kind of activity and I actually feel less worried and calm while its effects last. However, I don't know what to do with both of these meds. Please help. Tomorrow is very important for me and I am scared I would mess it up.
