Yes. Concentrate on today. Tommorow you will conentrae on tomorrow but tomorrow hasn't come yet. So you should only conenctrare about today. How will you live today? How will you recover today? Do you really have to act out today? Do you really have to look at that non-boy (thats what one of my Rebbeim called them ) today?

Shalom aleichem, Warrior!
Make yourself comfy- and stick around.

There's not much advice for me to offer, because you've been doing some pretty amazing stuff! Like getting out of your comfort zone, shmiras einayim, accountability software, friend, rebbi(!!). Phenomenal!

I am trying to climb this 90 day wall too, and whatever success I've experienced is only for telling get myself 'BH I am clean now. It's worth everything in the world. I couldn't care less about tomorrow.'
Ironically, telling myself it doesn't matter if I make it to 90, is precisely what been keeping me going!

Keep it up, and hatzlacha!

Don't worry about 90 days. It is a distraction. Do what you need to do on a daily basis and you'll pass 90 without even noticing. Too many people focus on 90 and then fall before or soon after hitting 90.
