hi,I had the problem yesterday with being faint. I did have a piece of bread to feel better,it did work. But I cant keep doing that on this diet so, I bought two more vitamins, I got calcium&magnesium mix 334mg of calcium and167mg of magnesium and I also got an extra C with 500mg. Currently I am taking DR Atkins basic 3 and Essential oils. Will it be safe to add the extra c and calcium? Luckly I didnt gain any weight back I am still at my 6 pound lose at 8 days on diet. I love this diet but I dont want to feel sick so maybe more vitamins will help.
