How to sleep when taking Adderall? I am experiencing insomnia side effects?

As a health care professional and someone who takes Adderall I would suggest a few options. First option, have you tried short acting 20mg tabs? You could see about 20mg Adderall IR BiD (2 times per day). This way you can control how you take it and when (7am and 1200pm). It should wear off by 6 pm. I changed to Short acting for that exact reason. If that doesn't work for you, try seeing if your doctor could switch you to Vyvanzes XR, because maybe a different C-ll simulate will works better for you (as different meds work different will different people). Of course I don't now your insurance, but last you could try asking your doc to try 15mg Adderall XR daily? 20mg might be lingering due to your dose being too high? I hope this helps, but please respond back again, if you need more help.
