The last two threads have got me thinking about this.  They say you shouldn't take Viagra more than once in a 24 hour period.  I usually go more than that between doses, but I've cut it close a few times with no ill effects.  Just wondering if any of you mongers have used it twice or more, say once for a morning date and again for an afternoon or evening date the same day, and whether that had any negative effects.

Having that much sex would be too much for me!!  I'm like the guy in his eighties who was told by a sex researcher that a man his  age would be lucky to have sex once a year.  When asked why he was smiling, the gentlemen replied, "Yes and tonight's the night".  One my all time favorites

Seriously taking viagra often has affected me the next day without taking more.  I find I'm horny get a boner more easily than usual.

It still works for me the next morning.  So if I had a reason to go a second full day/evening, I would take a very small piece of the pill.

When I have an overnight that begins at 6 PM and ends the next morning at 11 AM, I take a 50 mg Viagra upon arrival and another the next morning about 8 AM. That's two within 14 hours, and I've never had any side effects. I've found that, for me, Viagra begins to work more quickly than advertised. I feel the effect about 15 minutes after I swallow a blue pill. My two-pill regimen makes me happy in the evening and happy in the morning. Wish it were less expensive.

I keep hearing that the cost per pill is the same regardless of size, so buy the largest and cut it up.

Any drugstore can sell you a pill cutter

This is true. Buy the 100mg pills and cut them in half.  However, a huge factor in pricing is the type of insurance you have. Up until recently I had Medicare plus a very expensive Medigap policy.  The Medigap cost about $6000 per year (for a couple) but it covered nearly everything.  Even covered Viagra.  A 30 pill prescription (60 doses if I cut them in half) cost only $100.  Yup, $3 per pill. I was spoiled by this low price.  

But to save money I switched this year to a very inexpensive Medicare Advantage plan. It's only about $500 per year.  I have some higher copays, etc, but since my wife and I are in good health we figured it was a good choice.  Except I found out later that Viagra is not covered!  My pharmacist said the same prescription would now cost $1500. Yup, $50 per pill.  Yikes!  Good thing I still have a sizeable stash.  Not sure what I'll do when I run out.

alldaychemist.com    I got 60 100mg generic sildenafil for $82 including shipping (from India.)

END OF MESSAGE

Good pricing on Sildenafil, 90 20 mg tablets for around $90.

about a decade ago, I would multidose a 50mg, two to three times over a 24 hour period.  No problem.  However, I do not do that anymore, not for any side effect problems, but this darned refractory (is that what its called) period got longer and longer over the years, even with vitamin V.

Receive perscription for 60'20 mg tablet and 11'refills
Can get a t Sams Club for $120 and with "Plus Membership" $ 20
They will let me do a refill every time I come in.
Can pay cash at the pharmacy so it does not show up I the bill.

I used to purchase in Maylaysia or Brazil when traveling for work and was about 1/2 price of here but did not need perscription.
As for taking more than 100 mg have done so more than once.

Great deal.  Did they work as well as the name brand version?

I've only ever used generics.  Seem to all work the same.

divide a 100 MG pile by 4.. seems to work OK at that low level.. and they are brand name.. Kwikmed is pricey though
