I had a traumatic brain injury 6th months ago. Ive been prescribed adderall since I was 12-13 and I'm 32 now. Once I was cleared to resume taking adderall I noticed that it doesn't work anymore. I've switched to Vyvanse and back to adderall with nothing happening. I've also taken recommended supplements for brain health... Ive lost all motivation and ability to enjoy lots of activities that I loved before the injury. If anyone knows anything about this, I'd be forever grateful for some insight. Thanks.
