Now that I've got 13 pills left of my son's 20 mg Vyvanse prescription, which he won't take anymore for ADHD after our horrible experience yesterday, he said it made him incredibly anxious, I am wondering if anyone has tried it for fatigue, brain fog, and depression as part of bipolar disorder. I'll ask my pdoc if he has had experience with this drug but I'd like to hear from you if you have tried it or would have some advise. I'm steering into a major depression, isolating and fearful of the world. I've not been exercising and am looking for something to get me off the sofa too.
