When does it go away? I'm now on my 4th week on 90mg of Armour and still have really bad brain fog. Will it go away when I get to my optimal dose? Can't tell you how many times I'll walk into a room not knowing what I'm there for. Everyday blends into itself so I have no clue what happened on what day. Gotta say, when you think every weekday is Wednesday it's always cool when you find out it's Friday. LOL
