I have never done a Master-Cleanse but I would suggest first to eat for a few days, so you can also go to your meeting. For the flush you need bile and the bile production slows down during a MC. So eating for a few days to get your bile production going again is a good thing to do.
As I told you I never did a MC, I have only read about it. So may be you can go through the old messages and see if you find more information.

Hi, I've never done Liver Flush after MC, and Hanna is right about getting some more bile (I think there was a post by D. about Master-Cleanse slowing bile production), meaning eating for a few days before doing it. But while I was looking for that post by D. (I didn't find it, unfortunatelly), I found though another post from Pepe who did it. This is the link: //www.curezone.org/forums/m.asp?f=73&i=689. So, if you are going through with it - good luck. Tell about your experience tomorrow. All the best.

I did a lot of researching and reading before deciding to do the Liver Flush immediately following the MC. It's a good of time as any from all I read. I would like to know how my sleep will be disturbed and if I will be able to go to an 11:15am meeting or not... I just took my first Epsom Salt and water drink. What a shock! I have been doing SWF's for days and I had myself braced for a very salty drink. It's not really salty at all, just weirdly bitter and gross! How very interesting!

Oooh... very nervous about the next drink w/OO/GFJ! Have had a BM already from the first drink. Glad I did a SWF (Salt-Water-Flush) in the morning.

I didn't think the ES was too bad. Even the OO/GFJ wasn't too bad going down. I took some melatonin about 10min before drinking the mixture b/c I couldn't track down any ornithine. I definitely did not sleep well. I'm not used to going to bed at 10pm. It wasn't b/c I was in pain or uncomfortable, I think I was just anxious. Around 5am however I had to make a trip to the bathroom. I had a BM and also vomited up some of the OO/GFJ drink. It may have been not too bad going down but coming up it was AWFUL. I couldn't prevent it. Went back to bed after that. Instead of taking the ES drink at 7am this morning I took it at 8am. Now I think I'm going to go to my 11:15 meeting and take the second ES drink when I get home from it. I think this will prevent me from having embarassing buttpee while out. A little more time than recommended between the drinks but hey, I've gotta do what I've gotta do. I will keep posting until this thing is completely done and over with. I do feel pretty dehydrated right now. I am going to take a shower or bath... can I start drinking water yet?
