Absolutely. I practiced for 2 hours a day for many months after the course. Life circumstances forced me to take a several-month hiatus, but I'm now back to sitting for about 90 minutes a day. I can't attribute it to my meditation practice alone, but there have been some huge changes in my life since doing the retreat. I've become a lot more compassionate and accepting of myself and I've started to gain some major insight into the patterns of negative thinking and self-sabotaging behavior that I've engaged in for most of my life. It's like I finally found the end on the ball of yarn of all my negative bullshit, and I'm slowly starting to unravel it.
