Coming off 1mg

Joined a methadone program back in 2019 albeit for the wrong purposes and still messed around for a year. Once I found my stable dose I tapered very slowly once I felt ready, like 1mg every 2 weeks for like 2 years.

I was on 1mg for a few months as I felt unsure if I was ready to come off but finally said I am. Took my last dose yesterday and went to turn in my take home bottles this morning. Was wondering what can I expect these next few days? Even when they would test me my dose was so low it wouldn't even register in my urine. I'm excited to finally be out but also nervous about the changes coming, thanks for any tips and help.
