I was fearful when I did my first flush, rented a movie, took my Epsom Salts ...all the time kind of on edge just because I was a little nervous! Well...the olive oil and pink grapefruit mix went down smoothly and I even thought it was yummy! (fragrant - I like olive oil...reminds me of olive groves...) I slept soundly, awoke for a half an hour with a little discomfort (nothing huge by any means), went back to sleep, took my Epsom Salts ....slept again, then got up and released a whole bunch of golden stones - some the size of marbles! It was a piece of cake, basically...but I had worried about it. And the flushes HAVE energized me!
It sounds like you reeeeally need to do a flush...so, like Southern Belle says...treat yourself exceptionally well the day of and the next day...make a beautiful plan...get cozy. The benefits will far outweigh any discomfort...Then you will feel great to go to Mexico!
