@robertatheriveter - Glad to hear the sodium sulfate, magnesium sulfate and potassium chloride combination (SUTAB) worked much better to prep you for your colonoscopies.

You may have seen my post earlier in this discussion about trying the sodium sulfate, magnesium sulfate, and potassium chloride combination (SUTAB) pre-colonoscopy https://connect.mayoclinic.org/comment/1289181/. It did not work as well for me as the liquid and made me rather ill. Like you, I felt like I did not sleep well the night before, with setting various alarms at intervals to take more tablets and water.

My husband has done the PEG 3350, osmotic laxative and electrolytes combo (Golytely), but he has to start earlier the day before than recommended on the container because his system runs about 2-3 hours behind where mine would be having taken the same amount of prep.

All that to say, it seems that different preps work best for different people. But @michea, I'm with you that the whole prep thing is just awful. I guess you have to experiment with what prep works best for you and your body, though this can be a crazy experience.

@ggr - your doctor had you do a miralax and the gatorade mix, and it worked well? How did you find it better than the prep or preps from the pharmacy?
