They're working really well for me. They don't have any artificial sweetners, either.
I get them at my grocery stores, Christine. Krogers or Safeway here. They're in the pharmacy "butt aisle" ( as someone so appropriately put it) not the food section.
Like any fiber supplement, be sure to drink plenty of water with them.
