well done you! that's a fantastic achievement and I know you will make it.
Once you've reached it, I guess staying clean after that is more bonus for you! For me personally, I count it by month, and each new month I congratulate myself for going another month without it.
Maybe for your one year you could treat yourself to something you've been wanting or a day out or something? I recently got a tattoo for my 3 year free

I love them so that was a good reward for me, plus I can look at it to remind me how strong I am if I ever need reminding. Of course, your reward for yourself will be your personal choice, but I would strongly recommend doing something for yourself, you certainly deserve it!!
I'm always here if you need encouragement etc. I'm so happy for you, you're amazing!! I also agree with the above comment that helping around this forum might benefit yourself also, it means a lot to me if I can help anyone else, so it might make you feel good too.
