Viagra is a medication that is usually taken as needed about an hour before an erection occurs. Taking it too often can lead to a dangerous drop in blood pressure or other serious side effects. Many different medications can be used to treat erectile dysfunction, so if the recommended dose of Viagra isn't right for you, talk to your doctor about your options. Also, when taking Viagra, study the compatibility of Viagra and Caffeine, as well as with other foods and drinks.

So that a drink from fragrant grains does not harm potency, remember the generally accepted norm of caffeine for men, which is 400 mg per day. A cup of coffee contains approximately 100-140 mg of caffeine. From this it follows that you can drink no more than 3-4 cups of coffee drink per day. 500 mg of caffeine can already cause sleep problems, decreased potency and internal unreasonable anxiety. It is useful to know that Arabica has less caffeine than Robusta.
