Protein powders

Hi, I had my gastric bypass in 10/20. I lost 125 pounds and kept it off. However over the last year I started gaining quickly. Many things contributed to this mostly medicine, but was not eating as good as I was before. I wuit my job and took on raising my grandchild which put alot of slider foods in my house and not getting enough protein.I am having a revision next week. I am having a much harder time this round staying away from carbs. After my first surgery my taste buds really changed. I couldn't stand any of the protein drinks, and I was rarely hungry until late at night. I take adhd meds which keeps my appetite at bay. I have been trying to find protein powder and drinks that I like but still struggling to locate one. I am looking for a flavorless to add to food that doesn't taste gritty or chalky and doesn't change the flavor and a protein shake that tastes good.
