Hello - thanks for asking your question.
I agree with Erin's comments below. Either the Phosphosoda or the Nulytely would be acceptable. They work by different mechanisms, and patients may have different thresholds of tolerability to the medications.
Other than the prep and the dietary restriction, there isn't anything specific that you should be doing before the procedures. There should be conscious sedation with either procedure which should help you tolerate the procedures.
Followup with your personal physician is essential.
