Billy...I've taken them all (Levitra, Viagra, and Cialis), and the only one with visual things going on for me is Viagra. My vision gets very slightly yellowish or something, colors get slightly weird. As far as Ceebis (I get from ReliableRX, the ADC sister company that takes CC's), I take an unopened 16oz of regular drinking water and put the entire Ceebis 20mg pill in it. Seal and give less than an hour to dissolve, shake well. Drink a quarter, a third, a half....basically whatever amount you want to dose at. As for me, I drink a third once a day, it's about 7mg. I just eyeball it. The Ceebis dissolves perfectly, the vodka suggestion that thread started with is absolutely positively unnecessary. Since I drink a third a day, I get a new bottle when it's empty and do it again. It's very thrifty, as using the Ceebis this way the cost is low. And this is getting off the topic of what you asked, but I also put l-citrulline and l-arginine into my drinking water cup. It really helps as well.
