Day 3 and I'm already dropping stones?

Wow, this is so weird. I'm on day three of my second long fast and I'm already dropping what look like small Gallstones (found four). They are the same colour as the ones I was dropping near the end of my last 29 day fast (tan/greenish yellow). I just don't know if it's really coming from my gallbladder. The last time, it took 11 days before I started dropping over 100 stones over the remainder of the fast. Of course, I'm now taking chinese bitters, coptis and apple cider vinegar, but I'm surprised that I would start releasing stones so quickly. I'm kind of wondering if I'm thinking what is actually waste would be stones.

Anybody have any input on this?
