Jeff........I have never experienced the blue vision thing while taking Viagra. I know others have. When my surgeon started me on the RX Viagra, the insurance covered only 6 pills per month. So he advised me to split them, and take one every other night to nearly cover a month. At the same time, he sanctioned my using ADC. Once I got the ADC Viagra, he gave me the green light (not the blue one) to take it up to 100mg, and if no problems, fire away every night. So that's what I did. In the beginning, I didn't even get any plumping, but felt i was getting blood to the tissue. Then, over time, things started to happen, and now, taking the pill before bed, I get frequent nocturnal erections
