Vitamins and protein
The only protein drink that I ever could get down was Syntha 6 from the Vitamin Shop. When you open a container of protein mix and smell it, most of them smell like sour milk. The Syntha 6 smells like cake mix.
Chewable vitamins are usually sweetened with things that cause a lot of gas and diarrhea. You can take two multivitamins like Centrum or a store brand. I have trouble swallowing pills with water so take mine with a small amount of sugar free applesauce.
