Hi,

I've been using Cialis 5mg daily for about two months. I cut a 20mg in quarters to save money and often it doesn't cut exact, so I may get 4 one day and 6 the next... is this an issue?

Also, while it works fairly well, I do have some difficulty staying hard as long as I wish... can I take a "booster" perhaps another 5 or 2.5 pill prior to activity to keep hard?

In the past, I've taken the 20mg, which worked well, but limited the spontaneous sex. Could one take a 20 every two or three days and accomplish better results than the daily 5mg?
