haha well just keep trying, My friend has been trying to do the master cleanse for a year now and she cant get past the first day. I was having the same problem as well this year ..I would last 2 or 3 days. Even though, I have completed 29 days, 14 days and tons of 4 day fasts. I would say any length of time is better than nothing, as long as you don't give up.
