I'm trying to get access to academic articles around TBI research, but am finding that I have to pay to see full articles or have an academic login. Does anyone have tips/tricks for getting access to full research articles for free?

For context - I've had TBI symptoms for the past ~6 years, and my symptoms didn't start until 18 months after my head injury. I'm trying to pull together research around pituitary dysfunction related to TBI for a doctor I'm seeing - I asked her to help me explore this for my situation, and she didn't know about the research/believe me so I want to bring her a boatload of research to get her up to speed!

Thanks!
