Coffee kept me going too, but I stopped drinking it a while back. I'd recommend trying a few days without coffee (even if you're only having decaff). You'll be surprised how soon you get used to not having it; and stopping coffee helped reduce the urgency of BMs significantly.
Instead of coffee, I drink a glass of fresh vegetable juice that's been diluted with an equal amount of water.
