Has anyone had success taking daily doses of Levitra, similar to daily doses of Cialis? I have been getting constant flushing and muscle/joint pain with daily Cialis (even at 1.25 mg/day), which is a shame because I enjoy the benefits. I'm hoping that Levitra will have less side effects but still give me the same benefits of daily Cialis. I know that the half life is only 4-6 hours, but I did read the study where benefits lasted about 12 hours, suggesting that perhaps the drug has a greater affinity as a PDE5 inhibitor even though the serum levels may drop more quickly. I'd be willing to take it twice a day (so every 12 hours), perhaps 5 mg with each dose. Anyone have any experience doing that, and if so, at what dose? Any reason to believe that it wouldn't provide similar benefits to daily Cialis? I did see the study about daily Viagra, but have had side effects from on demand dosing in the past with Viagra, so I thought I'd give Levitra a try. Just wishing that it's pricing was a bit more reasonable.
