No, not for me at all, although I got rid of my last apartment thank God, it was full of mold and I'm a bit sensitive to that, so in that respect I felt better when not in my apartment, but had nothing to do with the mebendazol. The reason I was sensitive to the mold is that my immune system was so low, and when I got better I would not get as sick from the apartment. I'm not sure why you felt better when away. I got somewhat better during my first treatments with albendazol but some side effects as well.
