You can also do this and give yourself a waiting period. I think, Lrad, you mentioned doing this at night? So you can write it at night, then decide "OK, I'm gonna wait to see if I still feel this way in the morning, and if I do, then I'll send it." I've found this to be helpful. Because my T often doesn't reply till the morning, he suggested this, and it's kept me from emailing him a few times (typed something up at night, then chose not to email it in the morning, just shared in session).
