erectile dysfunction
"I am 56 just got back from 4 months in Philippines. I tried Viagra and Cialis. Cialis works great and had no problems. Vigra is good and maybe harder but a hassle waiting 2 hours after eating then about 1 hour for it to kick in. I took Viagra one time on empty stomach because didn't want to eat and wait. My eyes saw everything blue/yellow a few hours and slight headache. I prefer the yellow pill 90% of the time but keep a supply of the blues if the timing is right with meals. I return in 2 months and will make sure I have plenty of yellows and a few blues."
