erectile dysfunction
"46 yo, average health, no major ED but just not what it used to be.
Bought 100mg Viagra and 20mg Cialis to do a comparison (both name brand). Split the pills and took 50mg and 10mg of each respectively in separate episodes. While they both worked, Cialis is the clear winner for me. The reasons:
1. Lasts longer - Cialis lasted all weekend. We didn't need to plan anything.
2. Not affected by food - One time Viagra didn't work at all because I had eaten.
3. Cost - Pills are similarly priced but because Cialis lasts 2 days (and Viagra 4 hours) you don't need as many doses (nor would you waste a dose by accidentally eating)."
