ADHD will give you Organized, Dexterous, and Fast Learner, as well as their inverse.
If you start with any of these traits, then THEY WILL BE REMOVED by the mods mechanics.
Same applies to Bipolar with its temporary Wakeful trait, and any others that add temporary traits.
This can be used to get rid of bad traits to squeeze out some extra points at character creation, so thats up to you and your own level of self control.
Wanted ppl to know as I was disappointed when my character with ADHD lost his starting Organized + Dexterous on his first "I dont feel focused" day. I just admin-gave myself the difference in points.
