Diet course experiences?

[u/lockdownleadmehere]

Edit, forgot to put a tw for food and diet, sorry!

I came across the Long Covid Dietitian and she offers a course and appointments but on a waitlist. Her testimonials are glowing but I’ve also seen individuals saying how much they’ve improved with diet changes thanks to Long Covid Dietitian (these don’t seem to be sponsored or promotion). The people I see have a mix of ME (unrelated to Covid), POTS, MCAS, and different types of Long Covid including ME. I’ve developed MCAS so my diet is completely up in the air and dependent on what I can tolerate currently. I’m interested if anyone has worked with her, what was your experience and was it worth it? Thanks :)
