Do I have to buy all my required Opti at once?

What if don't like one flavour over another? Can I buy one weeks worth at a time? 

I meet surgeon on April 20 @Hotel Dieu and imagine I'll be buying that day?

You will be required to buy it ll at once. Some people split half chocolate and half vanilla. You can always add sugar free syrups or coffee crystals

Yes all at once. I did half and half. Personally I prefered vanilla. Just used sf vanilla syrup and lot of ice in my bullet.

Thankyou!! Is it really as bad as everyone says???

I am on day 13 and it's rough.  Not awful but I will be happy when I don't have drink it anymore.  I don't love the vanilla, the chocolate was ok.  I'm bummed I had to buy both flavours    

Wait, you need to buy both and can't buy say just chocolate?

Oh wow now I'm scared lol-I am a chocolate lover but maybe I wont be after I try opti- I wish they let you try samples before hand since its such a pricey purchase! I feel like the vanilla would have more options taste wise than choc..how many weeks do you have to drink it for? I meet my surgeon April 20 and am hoping for only 2 weeks..

I have been on Opti for two weeks.   Thruthfully it's not that bad.... I have 2 shakes left and then I'm done :-) 

That is too bad.  At our nutrition group class they let us try the opti.  Some of the nastiest stuff I have put in my mouth but for me the vanilla was far more tolerable than the chocolate (I don't really like chocolate)

I am on opti fast for 3 days now and I'll be on it for the next 3 weeks, it's hard but not awful, you need to be creative, I have the chocolate and I put flavor like almond extract, vanilla extract and coconut extract in it. And you can ad ginger, nutmeg and cinnamon in it (bulk store), my favorite is 1tsp of instant decaf coffee, ¼ tsp of nutmeg and  ginger and a few drop of vanilla and almond extract plus some ice in it to. So good luck with everything
