some herb teas can be really helpful. There is one called alpine tea which is really great for opiate constipation.

It is a red seal product - if that brand is not available where you live then you may be able to find something similar. When I have taken it, I had to make sure not to have it more than once a day esle I would get the runs. It is very gentle, and not habit forming for the bowel.

good luck with the miralax
