Tadalafil
erectile dysfunction
"No doubt that Cialis is one of the best. I'm 58 and have been taking the 20mg Cialis for several years with very positive and long lasting results. I've found out that cutting the 20mg by half still give a good and hard erection and alleviate the side effects such as headache, lower back pain and blurred vision. However, I think that Cialis could be better in a softer form for a faster reaction (It takes a few good hours if taken after food and drink)."
