Hello! Thank you for the query. You should not take more of Miralax. Please note that is can take even 2 days before you will excrete the stool. Miralax helps in holding the water inside the intestine instead of absorbing it. So you should rather drink more mineral water and increase fiber rich products. You should also start some physical activity (it stimulates bowels to work). And please remember that Miralax helps with the symptom which is constipation. But every constipation has a reason. It can be bad diet, chronic bowels infection, medicines (ca-blockers, antidepressants), hypothyroidism or even colon cancer. Hope this will help. Regards.
