Cialis is the one for me.
Tried sample of Viagra from my doctor twice. Both times: major headache, nasal stuffiness, and face flushing. Next day side effects were gone, but so was the wood.
For some reasoin it dulled the sensations during sex, and I found it less enjoyable than the odd time I got wood without it. Found it difficult to come.
Then tried 20mg Cialais. Have been using it now for over a year. Sometimes experience minor headache and nasal stuffiness. Face flushing as well, but that only lasts for the first hour or so. For some reason I am more susceptible to heartburn for a day or two. HOWEVER, the wood is just fine the first and second day. I even notice that there is wood improvement, though not as strong, on days 3 and 4 despite not taking another pill. Do not experience the loss of sensation & difficulty in coming that I did with Viagra.
