Help! 4 month sleep regression??

My son used to do great sleeping through the night. About 3 weeks ago he started waking up every hour throughout the night. His eyes stay shut but he kicks his legs vigirously and flails his arms and tosses and turns. I end up just having him sleep in bed with us (yes I know this isn't reccomended) and I just lay there half asleep most of the night holding his binky in his mouth as he tosses and turns all night long. he takes 6 naps a day sleeping only for 20-30 minutes at a time. I'm so lost as of what to do.
