My doctor has prescribed Cialis, which I've used to (mostly) good effect.  But, I ordered a batch from a place in India--since I don't want to keep getting Cialis from my regular pharmacy, where my SO can see my records--and they sent an extra ten of the blue pill.  I've used it (an hour before my sessions) and it's been great, better than Cialis.

Problem is, these pills came without any prescription or any directions.  So, my question is, How long do Viagra's effects last?  Enough for an entire evening (in an overnight situation)?

Any feedback will be helpful.

Thanks!

...4 hours according to the literature. My personal experience is in "stimulating" circumstances I have felt the effects for as long as 8 to 12 hours after taking the 100 mg pill. Believe it or not YMMV applies here too. My experience with Cialis was it left me hanging (literally) a couple of times so I quite using it. Go on WebMD.com and read about Viagra.

Lasts about 5 hours. However, If I take it late at night it is still working in the morning. But, then again I don't always use it . Everything just works a lot better with it. i take the 100 Mil. I also have tried Cialis with not good results. viagra works best if you don't drink any alcohol or eat a heavy meal  about 4 hours before taking it.

It depends on doseage..... for me 50mg lasts several hours thru morning.  However.... ordering from a place in India??  How do you know what your swallowing??  You say it didn't come with instructions!!!  How many legit med's have you ever taken that didn't come with directions and warnngs??!!  Its crazy to take those pills.  There is at least one legit legal online USA source for ED pills that does not require a visit to the Dr.  Use your other head.....

But if you check you will probably find that the legit place gets their pills from India. I buy from Secure Tabs. They do come from India and have never had a problem. They work very well.

i agree with you, authentic viagra is tough to fine withour prescription, do u have any online you know thats truly authentic

i ate 12 of them before a session with my atf...and only 6 of them worked!

good night, folks, i'm here all week!

Netdr.com is a reliable source for genuine Viagra and Cialis.  The product is shipped from a Brooklyn pharmacy.  However, the cost is more than $20 per pill.

lasts 3-4 hours which is more than i do, then fades naturally.  I think there is still some in your system 12 hours later.  The V pills can be cut.  My MD Rxs the 100s & I cut them in 4.  V  tastes like crap the reason for the coating...  more bang for my buck!    I've never tried overnight but I can feel some effects when I shower in the morning.

Or call another provider.

I get emails from a Canadian pharmacy.  Does anyone have experience with them?

Thanks

I've had an erection last longer than four hours. Not too long after four hours it started to become very, very painful. Extremely painful, almost unbearable. Fortunately I was able to get it down maybe around the six hour mark.

It was terribly scary.

As an Indian, I know there are good and bad companies. They make generic V, using the same formulations. Most patented drugs are available as generics in India . It takes them not more than a month to copy patent and manufacture in India. Kind of sad from a legal point of view.

Not......multiples, not an issue either....good vitamins!
