My suggestion for the salt water flush is, drink it from a lidded cup with a straw aimed for the back of the tongue. If you have it warm enough, you can trick yourself that it's just salty broth. I added a squeeze of lemon to my salt water, and actually enjoyed it! Good luck, do try to do the salt water, it makes a BIG difference.
Also, someone posted a couple of weeks ago about drinking a 40oz serving of hot water (temperature of tea, but just water) each morning. After 5 days of drinking that, she passed a poop rope!! I tried it and had better luck with BM's so give that a shot too!
