Why did you get this stuff??? Because you are retaining water, because you want to fit in your skinny jeans or because you want to change the number on your scale?
I'd be really careful with that stuff. It is nothing to monkey around with.
Diuretics are similar to laxatives in that the person *thinks* they are losing weight, when indeed all they are losing is vital fluids. Diuretics not only elevate your heart rate leading to heart arrhythmias and dizziness. Depending of the amount of fluid lost after the use of these pills you also mess up your balance of electrolytes within your body, which is another way you end up just asking for heart arrhythmias. In the end, you also regain back all of the fluid that you lost in the beginning and the body retains more water to try and account for what was taken out.
Diuretics are most commonly prescribed to patients with high blood pressure, edema or congestive heart failure. They are NOT intended to be used as a means of losing weight and can have serious side effects including increased levels of uric acid in the blood and hypokalaemia (low levels of potassium in the blood). Hypokalaemia has mild symptoms such as dizziness, headaches and muscle weakness. However, severe hypokalaemia can lead to an irregular heartbeat and muscle paralysis.
There are better ways to lose weight! If you are retaining water, try and drink more water. Cottage cheese and pineapple are working really well too - without the risks and side effects. If your water retention is severe, you need to go see a doctor and find the underlying reason for it.
