I've used Movieprep the last two times since they took the fleets prep off the market. The first time it was horrible tasting and hard to finish. This last time I added some lemon Crystal Lite and it was much easier to get down. I followed each dose with some ginger ale which helped get the taste out of my mouth. It also helped that I split the dose, one in the evening and one the following morning on Doctors orders. I could never drink a gallon of anything so I refuse to use go-lightly.
ps, even though movieprep says add no flavoring the pharmicist coulodn't think why adding crystal lite would hurt anything and beleive me it only helped.
