How to get the best results?

Taking Viagra for men, do not forget the following tips:

  • You must be in the mood “for that”: this drug starts working only when you are sexually excited. After each sexual act your erection will pass off, as it usually happens, and occurs if you have a sexual arousal again;
  • Things should be done when the time is appropriate: sildenafil works for four hours, you will agree that this is a long time to completely relax, apart from minor things and focus all attention on getting the feeling of satisfaction. Four hours Viagra can help as many times as you need. You should take a pill for 30-60 minutes prior to the scheduled intimacy. You may find out that the drug works faster. One-third of men’s action starts after about 15 minutes. The optimal administration of this preparation is in the prescribed dosage about an hour before sex;
  • Be careful with meals: the medicine can help you have an erection regardless of the meal. That means you can quite easily arrange a romantic dinner, during which you discreetly take a stimulant. The only thing we should not forget that if you previously ate a solid meal, the effect may come later, but with the same result;
  • Be careful with overdose: the drug helps most men right from the first or second dose. However, some men need more attempts. Do not give up. Sildenafil helps men solve problems with erection. Try to take the medication the next time. Remember that the maximum dose of the drug is 100 mg per day. Viagra can be taken every day without fear of any serious consequences. If the effect of these pills does not satisfy you, consult your doctor. Often the correct selection of the dose changes everything for the better.
