I treid viagra once and all I got was a massive headache no other effects, however I did find out after that you are supposed to take and not eat any fatty type foods for a while after. Do not be misled however viagra cialis etc do not make you any hornier, aoi bigger all they do is open the veins that deliver blood to the needed areas. Have also heard if you don't need them don't take them as they make no difference in that respect. However here affect can be amazin( if not expensive) to those who suffer from ED and have not been able to get ip up for ages. See your Dr and don't try those crap things that advertise as being the original blue pill etc they are deffo fakes. Remember if you suffer from ED and have for a while the effects can be amazing. Replies please.
