Hi all. On day 7 of vlcd and feeling hungry and sometimes woozy. I take 10 drops sl three times daily. My breakfast is a protein shake, my lunch is chicken and veg with an apple and protien shake in the afternoon and fish and veg for dinner. I am hungry all day. I have had good losses but i'm really hungry. I also drink over 3 liters a day and take potassium. ANy suggestions? thanks vickie
