Hi Cellgirl! I wouldn't drink any liquids once you start your Epsom Salt drink. From there on in you should just follow the Clark protocol. I drink *some* water (not a ton) up to 2 hours before my first Epsom Salt drink. That's it. (I'm sure your AJ won't hurt)
Hopefully you drank a lot of water in the morning and the day before, to ensure that you're well hydrated? Hope so!
Don't worry...after you get some stones out tomorrow you'll realize how easy and rewarding the whole thing was!
Keep us posted, Cellgirl, and I'm sending you excellent flushing vibes!!
