I'm experiencing gas, bloating and constipation. Is constipation a treatment effect?

  I have was on a low fat and low calorie diet for about 5 days before I decided to start the Alli program. In keeping with the program I maintained by low fat / low calorie diet, and since taking the capsules I have had no "treatment effect." However, this weekend I was celebrating an anniversary at a restaurant on Friday night and a house warming party on Saturday. On both nights I attempted to keep to the fat LOW, but a grilled 6oz fillet mignon Saturday and various finger food at the party I can only assume that I exceeded the 15 grams target. However, I have not had any treatment effect repercussions!

Is this usual?
