Protein Drinks... What can I do?

I am on day 4 of my 10 day pre op diet.  I have been drinking Isopure for breakfast.  I am not able to drink anything that resembles a milk product.  I go into automatic gag and purge on all diary products.  Is there some other beverage that I could drink other than Isopure?  This stuff is nasty and expensive.

Mix protein powder with soy milk or almond milk (unsweetened) or water or 1/2 one of those & 1/2 water. Unless you have been told clear liquids... then... well... not much of an option really. 

Best wishes on your upcoming surgery! 

This obviously depends on your doctor's instructions but post-op (I didn't have a pre-op diet), I chose, with my doctor's blessing, to go the natural route! I made my own drinks by making a basic soup mix and adding in chick peas /soya beans/ lentils for protein. I thin blended them to the correct consistency. 

The protein content is lower than a typical protein drink so I needed to actually drink a bit more. But it was easy to get enough

Try the Syntrax Nectars;  most of those can be mixed with plain water.  I've only seen the product online, so I don't know if it's available at a brick-and-mortar store.  I like their Cappuccino and Lemon Tea flavors, but there are also eleven other flavors.

I know that Isopure does a Low or No carb variety (Chocolate or vanilla, other flavors may be available) at my local GNC store.  You might find something there.

I also used Snapple Diet Peach tea with an unflavored protein powder.  Just put it into the tea and shake the bottle, or put it in a glass and stir.

I drink GENEPRO.  It is oderless and tasteless.  I mix it with Crystal Light and sip on it all day.  I get my water and protein in at the same time.  It can be mixed with hot or cold....so you can mix it with anything.  I order it from Amazon.
