I used Pericolace and then CVS's store brand. They both worked about the same, but....I was most successful when ALSO drinking prune juice each day. If you can't stand prune juice (I'm one of the strange people that love it), Sunkist makes flavored dried prunes in orange and lemon that are great....more like candy than prunes. Ya just eat them right out of the bag. They should be at all grocery stores. Start slow, though. Prunes are God's gift....they work. I'm mean they can REALLY work if you down too much. We need you out of the bathroom now and then so you can post as to how you're doing!
