I am now taking Zantrex 3 for the 4th day and have a suggestion to avoid sickness: eat breakfast let it settle for like 30 minutes then take 2 pills with a small snack and huge glass of water like 16 oz. (I don\'t like water so I drink sugar free juice or tea) and to avoid being sleepless, what ever you do don\'t take it after 1pm. I am also jogging on a treadmill for 20 minutes a day, and doing the intro to Atkins and I have lost 3 pounds already. (only day 4) Maybe this will help some of you clear up the side effects. Happy dieting.
