On my first Master-Cleanse
I broke my caffiene addiction, - coffee, tea, cola -and had terrible headaches the first 3 days. Day 1 was so bad I had to leave work because I couldn't even look at my computer screen.
DRINK MORE WATER!!!!!!!!!!!!!
Yes - you will have to go to the bathroom a lot but thats okay. You need to get those toxins out of your system and you will begin to feel better - believe me.
Be sure to do the salt water bath - that will also help.
Its very much like what a drug addict or alcoholic goes through in detox! It isn't very pleasant, but it is necessary. You are detoxing years of chemicals and poisons from your body and it is being stressed to the limit with all that being purged out of your system.
Good luck and hang in there!
