Interesting to read this today as i was experiencing something similar this weekend about the at work vs at home effect. I dont know yknow Vyvanse. I am on Modafinil. I actually noticed the opposite effect you describe where i am just aimlessly floating about when not at worl. I think it has been ore to do with the lack of plan and structure in my day. Meds are only one part of the treatment, for me making a plan and refering to it throughout the day is an essential part of managing my ADHD. When i dont have one, i feel aimless, then frustrated i go in circles and disciuraged i did nothing at the end of day and that can get expressed by lashkng pi ut at kids/spouse.
