Don't worry too much not everyone has problems. We always have slept with our dog and cats. Finally after 2 years of liverflushing I did the Dewormer, but I don't notice any difference.
According to Ask Andreas Moritz
(a different view) you don't need to do parasite
cleansing as long as you do liverflushes and bowelcleansing. When you are clean the parasites
have no feeding ground.
I have been doing these two flushes, and only once I saw some reddish liver flukes, and never again.
