I do not (36H here, too). I feel like after a whole day in a high support bra the girls need to breathe. That feeling of taking off the bra at end of day is delightful!
When I'm home sick, I had a few older pairs of very soft all cotton bras I used to wear. I threw them out when I lost all this weight though and I'm thinking about getting another one based on this thread. Maybe i should change into something like this at night when lounging. I have to go out in the street to walk the dog before bed, so I often don't change into night clothes until after that; maybe this is a good alternative to relax.
When travelling I use a sports bra, absorbs sweat, etc. yes it gives the dread uniboob a bit, but it doesn't chafe as much. Mine have a higher cut on top so under a v neck it looks like a camisole.
