Can I use Cialis or Viagra with alcohol? Drinking alcohol with these medication may end in low blood strain. Alcohol additionally reduces nerve sensitivity and can inhibit certain pathways that are needed for an erection. It's used to help get and maintain an erection for sexual activity. Higher doses may also cause priapism, a painful erection that lasts longer than 4 hours. Cialis doesn't affect your skill to last longer. Viagra will last for around 4 hours after you are taking it. Its results final for around six hours. I've achieved particularly well with brief term features in all of these purchases as the native sharemarket has had a lazarous kind recovery over the previous few weeks. It is probably going that Viagra lasts for round four hours for most males, and while it remains to be efficient, it may not work as nicely because it did after the primary hour. It also continued to be nicely tolerated.
