Hi. I haven't used Paragone (I'm about to use it for my kids), but I am now using the Old Amish Dewormer plus zapping. I have begun seeing "things." After only one day on the Dewormer/zap combination.
If money is a concern, the Old Amish Dewormer works pretty fast. It tastes good, too. At least I think so.
Also, you can take the OAD on a maintenance dose of three tablespoons a week. It should last a while that way.
