Whether "Viagra" causes accustoming to her? Whether Can it will turn out so, what in a consequence without "Viagra" at me will "not stand"?

[Rzheznikov M.V.]

Forgive or Excuse, if the need or requirement for reception exists, that, means other variants is not present. If such necessity is not present, what for.
And as a matter of fact a question, all pharmacological agents cause "accustoming", but it is a question that constant long reception of any preparation, kogda-nibud will lead to augmentation of a dose for effective action.
