Just started Medication and have a few questions

I started 15mg of Adderall XR on Saturday. I took it around 7:30, I ate a breakfast burrito before taking it...so some protein, not a huge amount but not too bad (at least I didn't think it was). I was shakey, felt like my thoughts were racing, and just generally "not good." That lasted several hours but not all day. I also felt like I was starving by 11. The only thing I noticed it "helping" was I didn't feel stuck in my phone. It was easy to pull away from it and I didn’t feel like I needed to carry it around playing videos. And after the shakes feeling stopped I wasn't as anxious the rest of the day. But I still felt like I couldn't get things started and had a lot of the executive dysfunction I have always had. Is this "normal"? Should I do something different? I just feel really defeated after reading about how people felt like it was life changing and so far all its done for me is let me put down my phone. Maybe its not ADHD maybe I am just not a good adult haha
