Adderall XR and "Visual Disturbinces" | ADHD Information

I am taking 40mg Adderall XR, and it helps with the ADD (alot), however I get minor "visual disturbes" when peaking.  So far I've counted 3 (TV like lines, color patterns, and seeing "shadowy figures" in the dark).  They are only a minor annoyance, and most people would not notice, but I'm wondering if anyone else has had this experience.  They mostly occur when I'm tired [after a bad night sleep, the next day]. xdxfp38518.8949884259
