Thanks for the reply, Matt contacted me through email but his protocols where a bit much for me so Iím continuing with the ivermectin/FenBen since they are available in Canada. The FenBen I have is powder and 99% pure not like the paste which I believe is only 12%. I mix it with a DSMO so absorption is higher. The first few days it caused some side affects like I explained in my original post but now there is no more side affects. Iím planning to do 4 days on 3 off of ivermectin for 2 rounds then do a 4 on 3 off of FenBen. Already I have had huge improvement but Iím not 100% sure if all I have is pinworms or something else on top of the pinworms. Possibly roundworms that I got from an infected stray cat we took in a few years ago, she puked them up so I know she had them. I did order Albendazole tablets from China through eBay but Iím not sure they will make it through customs or not.
