I have tried Viagra a few times during romantic get-a-ways (with my wife, of course). It is great.
I don't think you are supposed to drink alcohol while on it - but not sure because I got it from my brother-in-law and haven't consulted a physician. However, in my head (mind), the best thing about it is that you can drink all you want and have a rock-hard disposition into the morning. Great for occassional use, but the novelty (or something else) would probably wear off if used very often. Hope this helps. Frog
