Just recently had my interlock removed. I'm free!
It's a gratifying feeling, just work through it as another step on this journey. Do NOT blow a failure, it'll just start sending things down a bad path. I also wrote some notes on a dedicated blog about the interlock device I used, and also my 'backup' in case it ever registered a failure. Maybe it would help to read through and see it isn't something to be frightened of. My DUI was quite awhile ago but I putzed around getting everything taken care of. Congrats on your sobriety today, my friend. Here's the blog.
