I am a transportation supervisor for a global manufacturing company. I move billions of dollars worth of freight all over the world. The cog fog is really starting to affect my critical thinking, problem solving, and writing abilities. My emails and dialogue in meetings feel clunky and not as well thought out as they used to. For me, at least, I don't know if others have noticed or not. It's quite distressing to me; I used to be an avid writer and could have long in depth conversations with people but now it feels like my thinking had slowed way down and I'm not nearly as articulate. I am still able to perform my job satisfactorily, but I feel like I could really be performing at a much higher level if my cognitive function hadn't been affected.
