Pico Salax is definitely easier to drink. Sadly doesn't work for me, but then I am an outlier, almost nothing works for me.
I was interested in something involving pills - are you saying there is something where you can take 24 pills? I googled Suprep and I found: Each SUPREP Bowel Prep Kit contains two 6 oz bottles of solution. Each 6 oz bottle contains: sodium sulfate 17.5 g, potassium sulfate 3.13 g, magnesium sulfate 1.6 g. Inactive ingredients include: sodium benzoate, NF, sucralose, malic acid FCC, citric acid USP, flavoring ingredients, purified water, USP.
