I would definitely start easy and gradually increase the dose or it might give you some bad reaction... Going slow can never hurt...
I just posted my experince with deworming and increasing the dose was really a good idea, never had even a headache or anything - and now I'm seeing worms all over on my BM...
It's so silly to be excited going to the bathroom but I am..!! Wondering what I am going to see next. :)
Good luck!
