Welcome CTRL. It happens to many, what's important is you are trying again. What's also important is to figure out what you were lacking in support before that allowed you to have "just one" I use SR as my main support group, but lots of folks here use AA/NA, AVRT, or many of the other methods. You owe it to yourself to find a plan to keep you quit for good, read lots and ask lots of questions to help yourself find that solution. 100 days was a great run last time too, so you know that you can do it.
