Nice post, I always seem to go through a rocky spell when I move up. I think it just takes me a while to adjust. But this can be dangerous when a buyin is worth twice what you are used to and its easy to tilt/panic.

Now I will slowly dip myself into the level above for a bit before committing to it full time, eg throwing in a table or two on weekend evenings and probably playing tighter than normal for a bit until I get the feel for it.
