I use the Sutter coke flush with some modifications.
First, I still use epsom salts before and after. Before is probably not necessary, but I found that I needed to take epsom salts after the flush because I needed either the ES or an enema to help remove the stones and toxins from my body.
Second, I drink as much (apple cider/juice) as I want the day of the flush and after (to keep hydrated), however I don't eat any fat the day of the flush and I eat fruit only. Also, I only have lunch, never have dinner (just juice) since it would only get removed with the ES anyway and it would obscure the stones somewhat.
Definitely do what works but don't be afraid to mix and match. From trial and error, using a combination flush is what worked best for me in the end.
