Have you tried a coffee enema? I always feel better after one of these. You can google on here; it is pretty simple. Just get organic coffee, and enema bag from drug store, and leave inside for 15 min if possible. It will help flush out your liver, and feel better.
I use IF#1 to help keep things moving; Dr. Schultz's. It is amazing stuff for me, but just make sure you take it with food.
