I tried a generic Cialis called Apcalis. I split the 20mg tablet into two.
It took over an hour to kick in but lasted about 48 hours. The wood wasn't as hard as with 25mg Viagra. Also it gave me sort of an indigestion feel for most of the two days but didn't get any reddish flush that I could notice.
It's OK but for the money Viagra is better value for me. I will try a full 20mg tablet next time.
