I just wanna f-ing sleep at night

My husband is a damn bed hog. Last night i literally had 2 inches of bed so i tried to move on the couch but that thing is super small so i went back into the room and its like he sensed i got out of bed because there was zero room left on the bed. So now its 5am and im in the bath and ive gotten maybe 45 mins of sleep. This is an ongoing problem. Ive thought about sleeping during the day instead and just staying up all night but then i feel unproductive. Idk what to do anymore.
