Combining Cialis and Viagra

I was just wondering if anyone here has taken Viagra and Cialis at the same time. Given reports that Viagra seems to produce a stronger erection, but Cialis last longer, I was wondering if combining the two would give both. OTOH, it could be playing with fire.

The only difference (other than chemical) is that Cialis is eliminated from the body slower than Viagra so the effective dosage is a bit lower to prevent side effects. It's not worth the risk of side effects, which can be fatal if you have circulatory problems, known or unknown (if you're over 25 in a developed country you inevitably have some damage which only increases with age - sucks but fact). Also that erectile dysfunction (which Cialis/Viagra are prescribed for) is directly due to exactly the same kind of medical problems most likely to have bad side effects. No such thing as a free ride - sorry. This is one worth playing safe on - stick to the prescribed dosage and don't combine.
