It's definitely not for everyone haha. You get a rhythm with it, take lots of naps etc. The medicine does give you some energy to do the work, and you generally feel good from the vine. We take a couple months off a year and don't usually drink during those breaks. It's hardest when we ourselves are also doing master plant diets (even more restrictive than the usual "ayahuasca diet", no salt/oil/etc).
Always equally pleasant? No of course not. Some nights it's unbelievable and profound. The "hard" nights are still good as we're still learning to clean the things causing it. It's rarely mundane and (through the tradition we practice) there's always something to do, in ourselves or for our guests.
