Looking for what I think is a Teddy Pendergrass song?
 

I'm looking for an 80s ish R&B song that by the voice I heard makes me pretty sure it's by Teddy Pendergrass. The lyrics that I remember to it go "I want you so bad, I can't sleep at night, all I do is toss and turn" Does anyone know the name of this song, and if it's not by Teddy P, the artist too? Thanks
