I have done all the above except magnesium citrate as I cannot take this because it makes me deathly sick. Gastro told me not to take it but to use either miralax which has stopped working for me so I take 8mg Amatiza and a 200mg stool softener daily. Even take an extra and still need dulcolax sometimes. I take all the other things. I wish it was a dietary or vitamin/mineral issue.
