"I have Oxypowder but haven't really used it for more than a couple of days".
A couple of days is not nearly enough. You need to take the whole bottle over the course of time. Fasting is just going to make you feel sick, it dumps toxins too fast and your body can't handle it right now.
"The whites of my eyes are dull and I have dark circles under them."
That's a toxic liver your eyes should be shiny and bright with no dark circles.
"I also seem to have a swollen tongue; my tongue has teeth ridges along the sides. I do not know what this is from".
I do, you're digestion is compromised because the bile isn't flowing properly to digest food. You still have blockages in your biles ducts and alot of toxins in your colon.
"I am also an emotional wreck, but I have to say, it has improved since I started flushing."
YOUR LIVER IS THE SEAT OF YOUR EMOTIONS . Then keep going just when you think you will not reach success, it's actually right around the corner!
You got this! I wouldn't start fasting till all stones are out. Fasting dries up the gall bladder from not eating any fats
