Exactly, after day 90 the YH is not gonna magically disappear. Unfortunately if you're an addict, not even after 10 years. Forget 90 days. My advice is, focus on today. Every day is incredibly precious. How much is sobriety worth for you for today? How much would you pay to be sober today? (No guarantees for tomorrow). To me it's worth mountains of gold. I've been learning not to trade it for tomorrow and to value it more than anything. Today is the day. I want to have a good day, that's all I want. I want to be at peace with myself and everyone around. I daven to Hashem everyday, Hashem, please, please help me keep sober for today, just for today I need your help. I can't afford being not sober for a single day and I can't do it alone. If I act out I feel miserable, I don't work well, I don't eat well, I don't daven well, I don't sleep well and I don't love my family the way they deserve and I'm so ashamed of even seeing my wife after acting out. I feel fake. So please help me keep sober just for today.
Forget streaks and track records. I think they're a good measure of your recovery. But we must learn that simple truth. I can only stay sober for today, not for tomorrow. All that being said, if you haven't I suggest you look at 12 steps. I highly recommend Dov's shiurim as a starting point.
