I'm on Adderall XR 15mg and after an initial "holy fuck" phase for a couple weeks it's tapered off into a nice rhythm. Shit isn't perfect, but I'm able to get up and get shit done. However, I also have the "I'm not hungry because of Adderall thing. And the thought of eating right now disgusts me.". Which helps with the ADHD snack binges I've struggled with. So I'll take that over the upset/queasy stomach feeling I had with a non-stimulant med I took for a few months a couple years back

If I wind up skipping a day I'm usually fine and don't feel any negative impacts. However, I also drink a shit ton of coffee (typically black) so that could be helping curb any withdraw sysmtpoms.
