Opti Question
I found half a cup of water and 3 ice cubes was good, but I like mine thick. The first one I made I added too much water and it tasted awful. I would start with half a cup of water and at least 3 ice cubes and if it is too thick you can always add a little to thin in out. If you like coffee then adding decaf granules made it taste a little like an iced cappuccino. I found using a straw in one of those cups with lids for the first 4 days or so really helped as the smell bothered me at first. Best of luck - just remember it is only temporary, you can do it!
I used the amount of water the package called for 300ml but I add a whole cup of ice and blended it up until it was a milkshake consistency. The chocolate done this way was like a Frosty and I used da vinci syrups to flavour the vanilla ones, my favourites were strawberry or strawberry banana. I was one of those that actually liked opti which was a good thing because I was on it for 4 weeks. Good luck to you, stay strong the final step is almost here.
