With all due respect it was 1.5 years before I realized some of the parasites were ascaris. I realized this from the movement I felt and the vibrations they give and their length in my body. I took albendazole plus many others in dec of 2012 for 14 days and while it might have killed the juveniles and adults at that point. Well, lets assume it didn't kill the eggs. So, 1 dose of any medicine in my opinion simply isn't going to do the trick.
