2nd chance, glad to hear you tried it. It sounds like you had a great flush. The size of the stones indicates how blocked up you were. You might not feel great right aways since you stirred up so much junk. If I were you I would start taking psyllium to soak up the junk in you colon. Fiber really helps to clean up your colon. Also drink plenty of H2O to help out.
Again, it's great to hear that you tried the flush. There is a lot to learn about here. Stick around.
