Oh thank you for the comment. I've actually got 2 more I haven't written up yet. One I started today but it won't be until tomorrow or Friday that I finish it.
I had a month between the first 4 and the second 4. For me it was long enough, but I understand that everyone is different. For me, journaling everything I can remember the next day is a good start to the integration process. But then writing them as blog posts helps me process what happened even more. The fact that other people like reading them is just a bonus really.
