I over analyze too. Sometimes before I say something, sometimes after. I often times go the silent route if I think I've said too many things and I don't like the way they came out. Like the sentence I just typed.

As far as the talking to myself - that's pretty much constant - years ago I was able to stop it and I think eventually I'll be able to again. But, right now I just ramble on. Now that I think about it, I really don't talk to myself. I talk to other people they just aren't with me at the time.

OK. I think it's silent time now.....
