I don't do it regularly. But sometimes there's phases where I have so much going on during one week and I find it all so important and need to share it all (for example having loads of memories from childhood coming up and I'd feel alone if I couldn't tell them all). In these situations, T usually suggests I write the things down, and he will ask for the journal at the beginning of the session (or I can say that I want to give the journal to him). And then he will usually ask if there's anything he should read now (we'd not have time to go over the whole thing), and he will keep the rest to read. I print it out for him and write it on my computer to make it easier for him, otherwise he'd copy it, so that I still have my stuff.
