TMI-no pic: Can anyone recommend a better stool softener? 💩💩

I'm postpartum 2 weeks now and the one prescribed to me just doesn't seem to be helping! I'm drinking tons of water (8-16 oz an HOUR!) and taking docusate 3 times a day but these BMs are killing me. I had a 3rd degree tear and boy does it hurt! I don't need fiber cause bulk is not the issue. I'm just tired of pooping rocks! Anyone found something that works better?
