Did the skinny fiber work?

I took the Skinny fiber for 20 days straight and lost about 3 pounds with out changing my diet. I am pleased but for $59 I  would expect more. I got constipated because I think I needed to drink a lot more water. Well all in all 3 pound is 3 pounds, and I'll take that but since I ran out, I may try it at a later day.
