I’ve been on vyvanse for years and I haven’t noticed any memory issues! I also forget to eat, but I think that’s because it kills my appetite more than anything.  
Good luck!

My memory definitely improved on Vyvanse. I had memory issues when I was on adderall and the dose would wear off.

Has anyone experienced worsening memory issues while on vyvanse?  I started it a few months ago and saw some improvements in adhd symptoms but the last couple of weeks it's like I can't remember a thing.  Can't even remember if I ate or not.  I have a call to the doctor but wanted to see if others experienced.
