Is the 90 day program only for zerah livatala and watching porn? B"h i have filters and that isnt my day to day struggle now (probably would be if not for filters have succumbed to nisayon in high school as well as handful of times over the years when I first got exposed to internet-yes the taveh is dormant) however I live in a city where pritzus is unbelievable (young college university town people dressed as littlle as on the beach) and the constant challenge is shmiras eynayim on the street. Is the 90 chart for that as well?
Thanks

Yep - Let us know how it goes 

:-)

alternately you can simply move to a different city and then you won't need the 90 day thing

Welcome! There is no magic in the 90 day chart.  You are in a place of constant sakana.  Do you have any way out?  Avoiding the nisayon in the first place is the best option.  If you can't avoid it totally, what can you do to lessen it?
