Great to hear, welcome to the GYE family. Here's just 2 things you should look into to help you on your journey to 90 days:
Getting a partner in this struggle to give you support, you can do this with people you already know like your rabbi or a friend or you can sign up to the Partner Program here to get a mentor and/or partner from GYE. This may give you the accountability you're looking for and it for sure will help you when you're in need of support.
Getting a good filter, if you haven't already, so you put distance between you and unfiltered internet, you can do this by looking at a few free filters I listed in my signature or on Venishmartem.com. Venishmartem is a little outdated though so there are many filter services that aren't listed, there's one that I myself haven't listed in my signature and that's Google Family Link. Check that out also, it's another free filter service. And if accountability is what you're looking for I really recommend getting webchaver for free through venishmartem (the link is in my signature). Anytime they catch any explicit material with the screenshots they take, you will be charged a certain amount of money that you set. The stuff is reviewed by real people but you'll be anonymous to them.
