Sorry to hear of your hard day. We all know how that feels. I keep a trash bag and wipes in the car now, no matter how "well" I feel! It's just better for my ego and confidence to not have to poop in my pants!
Yes, if the Asacol doesn't help soon, ask about prednisone. Also, you might benefit from some rectal meds, depending upon where your inflammation is. Those have always made a huge difference! They seem really icky at first, but you get used to it and it's not as big a deal when you can appreciate the benefits.
Remidade was great for me. It put me in remisson for 2 years. so, I hope you can feel optimistic with starting it. It might just put you in a good spot without having to take a million pills every day!
