New to the world of gluten-free

What advice or things did you wish you had known when you first went to a gluten-free lifestyle? Tips and tricks for a newbie? Any gf brands or stores you love? Any input is appreciated just trying to crowd source information so I don’t have to recreate the wheel.

For context I just figured out I’m gluten intolerant (eosinophilic reactions) and I am still determining the level of intolerance and if I have any other food group intolerances.

Thanks in advance!
