I was recently prescribed 50mg vyvanse. They worked very well for me for about 2 months. After that, they stopped working. I just got my vyvanse increased to 60mg. Still, they aren't working. I noticed that I feel anxious & irritable on them. Will this eventually go away? I need them to work how they used to so I can get all my tasks done. I used to be so motivated & focused. I now procrastinate more, I get super annoyed/irritated easily.. I hate it. Any advice would be wonderful.

Anyone else have to go through this?
