It is important that this test reflects your body chemistry without interference or effects from drugs, supplements and chemicals. 1. No Tylenol, Advil, Aspirin, Ibuprofen, Aleve, Nyquil, Benadryl, or any other over the counter (OTC) medications for 3 days. 2. No coffee, tea, cola or chocolate for 24 hours. 3. No soda or other carbonated beverages for 12 hours. 4. No gum chewing, candy, cough drops, breath fresheners for ½ hour Regarding the use of nutritional supplements: 1. Activator will not have any effect on the results and may be taken. 2. If I recommended a supplement for you to take go ahead and take it, however, you must know exactly which supplements you took. Please don’t arrive saying, “I took all the stuff you wanted me to take” I will ask you precisely what you took and when you took it. You must be prepared to give me a precise answer. This will expedite the process. 3. If you are taking supplements on your own (which you should not be doing anyway). Definitely DO NOT TAKE THEM for 3 days before the test. Regarding the use of prescription drugs: 1. Try to limit your prescription drug use as much as possible. 2. If you take a drug in the morning, delay the morning dose until after your test (if possible). 3. If you take a drug in the evening, skip that dose the night before the test (if possible). 4. If you have any questions, call the office. Please be ready to give a urine sample on your arrival to the clinic. However, Do NOT drink excessive amounts of water in the morning, drink normal, healthy amounts. Excessive water intake will affect the results.
