no ropes

After a 2 week rest from my last 10 master cleanse I am on day 2 of another one. I have continued with the p& b shakes right through.I cannot seem to take more than 2 shakes a day without plugging up solid.I have tried the salt water in the am as well as the cider vinegar chasers but they don't seem to help. I have always been regular at least once a day and this concerns me and is uncomfortable.
I cannot get up to the 3 4 or 5 shakes that is recommended and as of yet have passed no ropes.
should I: be more patient?
try 1/2 a tbsp more frequently, instead of 1 tbsp
2x daily? I am hesitant to take a laxitive

Also has anyone tried pancreatin? will this help?
Thank you in advance for your response
