They are great for a little reset. Have you gone longer? That gets intense!

Longest I’ve tried is 18. I used to do 16 in the past and then 14 everyday for years now. I’m enjoying it so far.
You do longer?
Yo! A couple of times a year I do 4 or 5 days - very hard (especially with 3 little kids / my patience!) but surreal feeling and very good for me.
