Mouth got very sore this week, but was given OraMorph to conmpensate. Also entered 3rd week of constipation. However, some laxative (Co-Danthremer) and Prune Juice shifted this dramatically today..Found that Glycerin supposotories eased the way..I was prescribed mainly codeine for pain in the early part of the treatment and I believe this is worse for causing consipation than other (stronger) pain meds. This is now the half waymark of the treatment..roll on another 3 weeks.
