Feeling Super Spacey?

Ashley
Hey Everyone, 
I'm just over 15 weeks and feeling super spacey. I feel like someone could come wave their hand in my face and I would just stare (probably a bit of an exaggeration). I can't focus at work or even reading a book. I felt it in the first trimester and it had sort of died off but it feels like it is back with a vengeance. 
Anyone else feeling this? Anyone else have tips to feel it less?
