Thank you so much! Yeah, I am now trying adderall XR generic after trying the IR generic and having such bad nausea that my doctor took the pills back early and gave me this new prescription. Today was my first day taking the 20mg dose and it made me feel nothing really other than really tired all day. I read that this could be a side effect and would go away as I continue to use it. If that is so how long would that take roughly? I’m just unsure how long I should give it a try until I know for sure it isn’t working or isn’t the right dose.
