I took 16oz of prune juice and now im really worried that im going to have bad cramps tomorrow. will a digestive health probiotic prevent this from occurring? or is there anything i can take to prevent cramping from prune juice?

The actions of prune juice work on a simple basis where the sugar in the product draws water along while it stimulated an evacuation. Probiotics will not cancel this mechanical process. It may or may not trigger cramps based on the excess volume you ingested. I suppose Imodium may reduce the intensity of any cramping, but it may proceed regardless.
