Took according a leaflet the whole pill of Cialis of 20 mg. Cialis started to work about in 20 minutes. The effect of Cialis surprised me, sex all day and night. Generally, for my body action of 1 pill of Cialis lasted 3 days though I felt the maximum effect of Cialis in first two days.

Problems after taking Cialis were the following:

I could not finish coitus for a long; probably it depends on my organism. Without Cialis I can successfully finish coitus twice a day. After taking Cialis number of successful coitus increased up to six times. I had slight headache, eyes stress. In couple of days, before sexual activity I had half a pill of Cialis. Cialis started to work about in 25-30 minutes. Effect is the same good as at the whole pill. Side effects have not been observed.
