1. N/A 2. I have the most trouble with L's and P's. One thing i noticed is that usually pws have trouble with the first letter of their name (mine starts with L so that's that) 3. There are bad days and good days, and stress and anxiety usually worsen the situaton. I'm also pretty much completely fluent when i'm drunk. 4.I'd say you get used to it, but it's definetly an obstacle. Even if I'm not emotionally bothered by it, it gets really annoying, especially when I'm asking for things. I hope this helps you!
