Stopping Will cause a lot of syomachpaim and obstipation but maybe I can try…

Hello Brenda, this is a familiar laxative of polyethylene glycol. Here is a link to the emc database for this medication

I'd strongly recommend that you discuss this with your doctor and certainly before stopping any medication. There are certainly several alternatives to Macrogol which the doctor could recommend/prescribe if clinically appropriate for you.
