Tabithatwitch, love your name.
I am not laughing at you, but I did chuckle when I read that you are literally full of💩and you are going to quit eating. I have had both for 17yrs. You have been through a lot and are getting lots of good advice from others so I will just use a list, good and bad, these are my personal experiences :
Enema: I have given myself many, it doesn't go up inside far enough. They can be very helpful. If you have never had one, they are an irritant and you will want to poop asap, the pressure is intense. The longer you can hold it in the more productive it will be. I get prepared with a towel and pillow, and stay on my knees (I don't lay down) as the pressure builds, I rock back and forth, it seems to lessen the pressure, then rock faster, count to ten, then again, anything to help you hold it in. I had success with Fleet enemas. Salt enemas were a painful failure.
I don't know if after your type of surgery you have to be extra cautious or not.
I currently use 3 capfuls of miralax and 5 Metamucil gummies, 1-2x day as needed. Sometimes I go straight to explosive diarrhea, or mush, or it takes 2 days to get moving.
I have been having X-rays every few months for years, only 1x I was normal. A few had mild poop, most showed heavy fecal load.
I would love to use food/yoga ect but I can't. Example with prunes, I ate 10-25 per day and got more backed up and gained weight.
I am simply too exhausted and in pain to wait to see if prunes or exercise might work. I just noticed that this is a year old post, so... I hope you have found your sweet spot and are doing great. Shelley
