Optifast

I used LorAnn Oils which are available at Bulk Barn. Unlike flavouring syrups, they have 0 calories, and you just need a little bit to get flavour. The bottles are usually found at the checkouts because they are small enough to steal off the shelf.

I would also make/buy decaf coffee, put it in the fridge overnight, and then add it to chocolate OptiFast for an Iced Coffee. Even freeze some coffee and use that instead of plain ice cubes.

But remember, the OptiFast is a PRESCRIPTION, so please treat it as such. Too many people don't use all of it because they don't like the taste. I don't care for Buckley's but I'll down it for a cold. It's just for a short time, so down the hatch!
