I took this drug several times and the effect was above all my expectations! For the first time I took 60 mg dose and I got severe headache. The result was as promised – no premature ejaculation and the possibility to have a real good sex. I could wait until my wife came, and then I ejaculated. But the next day I had headache. So for the next time I reduced the dose for half and took only 30 mg, and wonderful! I didn`t have any headache. In sex the results were OK too but frankly speaking I need more concentration for the ejaculation.
