How often can you use Epsom Salts BETWEEN flushes???

I finished my 3rd flush 10 days ago. I tried the massage thing I've read about here and I actually passed one fairly large stone. However, 4 days ago, I started to experience that familiar, awful "indigestion"-like pain. I think the massaging worked, but it took a few days. I know I am passing a stone, even though there's very little pain on the right side (by the way, does anyone else experience the indigestion rather than pain on the right side???). Anyway, I had the "indigestion", Sunday evening, all day Monday, and a little bit on Tuesday. I passed a few small stones. I took Epsom Salts on Monday and within a very short time, the pain went away. When it came back on Tuesday, I was too afraid to take Epsom Salts again. I plan to do another flush this weekend, but was wondering just how often we can take ES without totally dehydrating.

Just to let you all know that I so appreciate this forum, and even though others are starting to encourage me to get the gallbladder out, I'm determined not to go under the knife!

Chimo from the great white North!
