It is miserable thing to have....I do hope you get some relief soon.
Try prune juice. It was the only thing that worked for my daughter, and I used it myself when taking codeine and struggling a lot in that area. I found the meds and tablets of little use in comparison.
Take a small glass of it three times a day to start with, and then once a day once you are more comfortable. It tastes ok, and it's natural and full of vitamins too
