Well done on 90 days. It was a big milestone for me too. I never thought I would last that long so I never kept track of the time.
No one was more surprised than me when my sponsor told me I had reached 3 months. I was too busy on the steps to notice the time I guess, but it is amazing how things change when we get busy with the program. By 90 day I was certain I was on the right track. Sounds like you are too
