8 month sleep regression

Did anyone go through this? My daughter used to sleep amazing 3 naps (30 minutes each) during the day and she was sleeping from 630pm to 530am consistently. Last night she woke up every hour at least and so far refuses to nap today (Lord help me). We'll see what happens tonight but I wanted to see if the sleep regression started like this for anyone else? Wonder Weeks said she was going through an exceptionally fussy phase yesterday, it's been pretty accurate so far.
