I haven't been sleeved yet, but I used to be a vegan and plan on returning to it. For the first couple of months or first year i will probably be peco vegetarian. Vegetarian and vegan products have really bombarded the market. Vega has some great 20 gram protein shakes. There's a vegan protein weight loss shake pgx satisfast with 20 grams. Garden of life has a whopping 28 grams. If whey is your thing body fortress has 30 grams for one scoop/ 60 for 2. All low carb/ low sugar. Hope this helps.
