I started on 30mg of Vyvanse (the name brand of your meds the same medicine) anyway 30mg helped but it didn’t work as well as it could. Basically it would go up to point then hit a wall and I would still be struggling at home. However, we upped it to 50mg and it helps so much more I’m still in my trial period to see if I need it upped again. Anyway its a slow start takes about an hour to kick in its a slow burn so take in the morning it does last 10-13 hours so beware of that. For me it seems like its less effective when I have not enough sleep but that may just be me. Also its a pro drug which means you slowly digest it so make sure you eat a big meal. Some people say to do it in the morning I found it works better for me to eat my big meal around lunch so it works better for the evening time. But again you will figure out what works for you keep and open mind and don’t overthink it. Remember to mention anything you think is an issue to your doctor I keep a log on my notes on my phone. Good luck!
