OK I just went to the doctors for the first time and she said I needed some protein drinks to mix with water my paper said

Less than 7grams of carbohydrates

25~30 grams protein (each portion)

Google is your friend..there's so many kinds and so many flavours

Premier protein shake has 30g protein, 4g carbs, 1g sugar. Various flavors to choose from.

there are tons on the market. I'd suggest picking up some individual packets (online or at stores) to try them first before buying a big tub of something that you end up hating.
