By the way what strength is the Prazi you bought? Apparently the dose is 25mg/kg of body weight.
I'm about 11 stone or so, which is apparently about 70kg, so like, 70 x 25 = 1750mg. That means I need to take... well, ideally about 4 1750mg doses.. doesn't it? O.O That sounds really high...
Also some of these products also have other dewormer ingredients in there and stuff too, so watch out for that!
