I’m 48 and I feel 20 year old again just taking 25mg Kamagra on an empty stomach. I pre-dissolve it in water and drink it up. The drug begins to work already in 10 minutes. As for the side effects they are very mild they don’t prevent my life at all, just only stuffy nose and sometimes a bit headache. But it makes me to be very active for about 4 to 6 hours, and I don’t need much time for `recovery`. I think it is a great medicine, but you don’t should overuse it. I should not advise you to take it everyday, but once or twice a week is really helpful.
