Sleeved 10 weeks ago. Lost 53 pounds since surgery. I have Premier Protein drink everyday for breakfast. I usually eat chicken, tuna, sashimi or beef for either lunch or dinner. Little snacking in between meals. Been taking Biotin plus a handful of other vitamins as well. Additionally, I will drink another Premier Protein drink after a vigorous elliptical work out, which I do 5 days a week. Vitamin water is excellent hydration, no calories, no aspartame. My hair grows significantly slower then prior to surgery, but has not fallen out. I think the protein and Biotin are key.
