I cannot drrink the salt water flushes at all! I threw up the first sip right away! I guess it just has to do with our mind-set. (I don't have a stomach of steel). I wish I could keep it down. One suggestion recently was to pretend it's soup and sip it.
I have a hard time keeping the B&P shakes down (they don't taste bad, but not good either). So what I do after drinking one is lay down and relax - this prevents me from throwing up. Perhaps one of these suggestions will help! Good luck!
