I'm really surprised you felt so down after your trip. I've never felt quite like that after being touched by mescalito. But like ANC said, with mesc the benefits may not reveal themselves immediately, at least IME. Everything needs time to sink in. I remember after my first experience I was in pure bliss for a few days afterwards. No drink, no smoke, no nothing.. didn't need anything.. I was already on cloud 9! Throughout those few days I began to become aware of why I was feeling so good: My spiritual healing had commenced. And ever since I've been trying to build on it.
We all have our luggage going round and round the conveyor belt of life, but it's up to us to sort out which ones are important enough to pick up, open and rummage through.
