Ok guys so I recently started daily Cialis at 2.5mg every morning. I noticed slight headaches a little upset stomach, good pumps in the gym and easier erections. After a couple weeks my side effects went away which is good however I noticed the sexual aspect stopped happening too. I've since bumped it to 5mg a day and same thing, no side effects and no significant increase in erections like it was before when I first started it. I'm gonna stay on 5mg a day for the cardiovascular benefits however next time I get lucky how much should I take before sex? 10mg? I don't wanna take too much but clearly I'm building a tolerance. What gives?
