Well if you have C you will be lucky if you have any luck. There is exactly 133 ml in a Fleets enema which is saline solution. How do I know? I use them whenever my IBS is bad. Somestimes I have to use up to 3 to get any real relief.
I guess from what I have read here it depends on each person. I have never found them to be worse than Golytely. You don't have to drink them......lol.
Good luck sweetie.
