I got back on it a few years back after realizing that normal people didn't seem to struggle with problems I just took to be my own lack of willpower.
I occasionally take breaks, sometimes weekends or weeks. I've noticed when I get off of it, it is basically the same as when I had depressive episodes. I start to feel completely lethargic, don't care about anything, I want to sleep and I consume all food within a 10 mile radius. I've notice the same thought patterns coming off of adderall as I do when I am depressed. I don't care about anything, I don't want to exercise because who cares, eat a box of donuts, sure it feels good now, and who cares about later.
When on adderall I can be shorter with people and get angrier quicker; however I am also less likely to act out because I have better control of my angry impulses and am able to recognize it for what it is. I also don't deal well with distraction on adderall because I want to just go go go and focus on one thing. Take that for what it is worth.
