NG,
Because you have offered advice and help to so many, here is my unsolicited advice for you! :roll:
I would try to cut down on the Vicodin if you can tolerate your pain. Never had LIS so don't know how bad it hurts. I try to avoid all pain meds and usually only take Tylenol even after surgeries.
I would start decreasing your Miralax by small amounts. I try to decrease or increase by 1/8 teaspoonfuls which is a very small amount. I would continue decreasing daily until my BM's were less frequent.
I would try to get back onto a more normal schedule. Our bodies are ruled by our individual circadian rhythms. That is one reason persons who fly to different parts of the world have so many problems sleeping, etc.
Cannot advise about the diet since I haven't had the procedure, but I think your body needs food and nutrients to heal. Maybe try drinking Ensure if you are afraid of eating various foods???
Each time you have a discharge, I would tell yourself, "this too shall pass." Worrying and fretting cannot help any part of your recovery. Try to be more positive about the final outcome of your LIS.
Hopefully, some of those suggestions might help you feel better and heal more quickly!
