Of course you can! Sharing success stories are part of what makes 7CupsOfTea become 7CupsOfTea. But, it isn't recommended, as 7CupsOfTea is mainly used for helping others, not bragging about your success. :D
My success story: My friend was struggling with an eating dis order, so serious she could have died. 7 cups helped her, and she is healthy as can be now =)
I don't think this would be possible from the role of a member or a listener.
