First day of Opti,
I blend my vanilla in a Nutra Ninja with ice, a package of Crystal Lite Tangerine Grapefruit and a drip of LorAnne's Orange flavouring (also have peach and amaretto so will try those next)- blend with ice and cold water and it is palatable (not good but you can get it down! _ I threw up the first two I tried even blended until I added the flavours).
