Thoughts on certain diet restrictions?

I’ve been stable for about a year now after finding out I’d been dealing with something called Anti NMDA-Receptor encephalitis, and like many forms of encephalitis, I get lots of vague answers about certain things. Now that I’m in a healthier/more stable place in life, the main argument I have with people is what my diet and lifestyle should be. I’m an early 20’s (F) and I’m finally back in college, I enjoy a drink, and coffee, and processed foods like anyone else, but my parents get nervous when I have such inflammatory foods. My neuroimmunologist always just shrugs and says that he never was a normal college kid so he doesn’t know how to direct me in that area of life. I’m doing IVIG on a regular basis and taking Lamotrigine, as well as getting ready to start Rituximab. I feel fine eating what I do (yes I eat normal healthy foods too), and every study about alcohol and caffeine and stuff is referring to people who consume unhealthy/ addiction level amounts of it. How has y’all’s diet changed based on your diagnosis?
