I slow my roll so to speak rather than try harder to get it done. I may do repetition until it lets go or just what ever happens happens but I force myself not to dwell on it or worry about it at all. It is what it is, like goes on, I may continue on without a second thought or I may stutter more, either way I don't dwell on it because that just makes it worse in my own head and translates into more physical tension.
