I read that bridgesii has somewhere around 18 alkaloids and peyote has like 64. I think pachanoi has like 6. I don't recall feeling stiff the next day, but I think any 13 hour trip would wear out the most experienced of travellers. The lotus blend sounds like a very delightful experience! When I take cactus I try to take it early in the day, because sleep is next to impossible. There is that moment, just before it kicks in where it feels like you could sleep, but once it takes hold, you just gotta hang on for the ride. A lot of people tend to get stuck (just don't wanna get up) and that's when I say let's get up and go explore, which is usually very rewarding!
