I have taken Adderall on and off my whole life. My doctor prescribed me 10mg of XR I normal take this for about a month and then will jump to 20mg. I just went back on it and I am experiencing insomnia side effects... I take it every morning at 8:00am on the dot never abuse it. I eat normal maybe a bit less, drink a glass of water a night before bed. unfortunately, not taking it isn’t an option for me as it helps greatly. Any suggestions would be greatly appreciated..
