Ditto. I've actually done the 10-day course a couple of times (highly recommended btw). One thing that amazes me every time is how busy/noisy urban life seems afterwards. It generally takes me a couple of days to readjust.
Unfortunately I've been unable to keep up the practice for more than a couple of weeks after I get back from a course. I'm not even sure why ... I really enjoy it when I do meditate daily. Something to work on.
I really should do another course (http://www.rasmi.dhamma.org/) to see if I can get back into it. When I do go back I'll probably follow it up with a 10-day stint of kitchen duties as well; about time I gave back.
