I would be pissed too. Matter of fact I'm pissed at the whole state of Florida for messing with my program. From CO. No medicaid here so it's been hard to get my meds plus strict laws. Adderal does suck in comparison to vyvanse and the timing is ******. You can be very on edge stopping vyvanse suddenly, not to mention not being able to pay attention and remember for s***. I would just be polite and tell the truth about your situation. That it's bad timing for right now and that you'd be willing to stop your meds or taper from them at a more convenient time. I doubt they would think you're just pill seeking if they've been treating you for a few months already. Just don't sound upset and speak the truth. It's a very legit reason to postpone stoppage of your meds. They had to go to school and study too at one point.
