Tadalafil
"I'm 51 yrs old. I'm active and a regular at the gym (5'9 210 lbs). Healthy non-smoker and social drinker only. I've been single and have not dated in years after a bad divorce. I meet someone a few months back and, surprise! A shocker, ED reared its ugly head. My MD prescribed 5mg daily and  goodness gracious! I hear people are having (some) bad side effects, but our only issue is soreness ;)  I'm loving my life now and we have only one thing to say: Fireworks all around, Thanks Lilly!!!"
