Milk of magnesia worked for me. I also did not have a BM until 5 days out. Make sure you get your water in and take walks. Anesthesia and narcs slow everything down and constipate you
The dietitian in my surgeon's office told me that I should be eating no more than 800 calories per day and that I need to be doing cardio 5 days per week. Have you discussed with your doc what amount of calories and exercise you should be doing?
