I had Prevx for a year and I only had a few (maybe two or three?) infections over that time. I don't remember what kinds of infections I had, but they weren't serious ones from what I remember. It seems like anytime I ran the program, there were never any infections, etc. Maybe, I wasn't on the internet as much as others, and so I am not the kind of person that is at high risk for infections. I don't know. So, I am wondering if I could do almost as well without Prevx. In other words, it has been hard for me to justify purchasing it again because the benefits don't seem to outweigh the expense. What say you, I am wondering? Thanks for the help.
