i find one of out three times  Viagra  100mg has only modest effect .  compared to the other two times ..  no i dont eat a heavy fatty meal before.    almost always on near empty stomach and yet still sometimes barely feel much.  

But if you're taking them on a fairly frequent basis...I would guess that the body would build a tolerance to it, like any other drug.
Just a thought...

It may not be the Viagra but the company or your mood/stressors.  
However if it continues try a script for another PDE5 inhibitor such as Levitra or Cialis.

I'm pretty sure after a certain age and if having serious ED issues, V won't help.  

100mg is dang high. Next time try a can of Red Bull (High caffeine). Are you on any other meds? If its a doctors script, I doubt they would mix and match meds on you. Other conditions? Diabetes is a big one.

good questions but i have no excuses .  i am maybe a few lbs overweight .. ok 25  lol ..but otherwise in good overall healthy.   i did recently start LIpitor but inconsistency has occurred before that.      mmm red bull with it ..  interesting .. cant hurt ..   heck if i have a heart attack with the next lady the biggest problem will the 40 minutes it will take to get the smile off my face!    

Tadalafil (Generic Cialis) for me is much better than Viagra. No nasty side effects like dizziness and vision probs, and Jr. responds well each and every time.

It tastes bitter as heck, but dissolving viagra under the tongue will actually deliver a stronger dose to the bloodstream then swallowing it.  Also it is said that drinking grapefruit juice will also increase the dose delivered through the stomach.  You can drink the grapefruit juice a few  hours earlier, not necessarily with the V.  The juice does something to the stomach chemistry that lasts a while.

The grapefruit or grapefruit juice bit of advice has some science behind it.   It is known that grapefruit contains substances that inhibit the Cyp3A4 enzyme which is responsible for metabolism (i.e. destruction) of most drugs, including Viagra.   Also, under the tongue (sublingual) adsorption of the drug is more rapid.    So, yes, I agree.    100 mg seems like a huge dose.   Half that has been more than enough for my own needs.

The older we get the more our overall health impacts erection quality/consistency. A great erection is not limited to people with great cardiovascular fitness. But cardiovascular fitness still has a strong positive influence on ability to get hard and stay hard. Especially as we get older.

Good advice on under the tongue, but a no-no on grapefruit juice.

like statins, react unfavorably  with grapefruit juice.   Check with your doctor before you use it with any drug.  

that grapefruit juice was not good for vasodilators...I heard same stuff that CDL said. I've thus avoided it. I do like citrus and grapefruits in general.

They may save your life, but may cause ED issues. I find that 25 Mg or 59 mg have about the same impact. As I age, I find suddenly semen production is way down. I'm 71 now.

I agree. Blood pressure meds definitely have an effect. I talked wth my cardiologist about it and he halved one of mine (Bystolic) to see if it helped. I don't see that it made a hell of a difference. I'm not getting the hardness I used to get but I still can get off and pleasure my partner.

Interesting, good to know.

Semen volume is way down for me too, at 70.  Some girls have noticed with concern, felt they failed me even though I fully enjoyed.  I take no blood pressure meds so far.

I use cialis.  Also viagra 100mg.  If I drink alcohol it affects the efficacy.   Also being over weight does as well. After I lost 10lbs and stopped drinking it always works.  I take 100 MG because I don't want to worry about it.  And worrying about your bones even if you can get one can deflate it.  Lol.  

There are multiple reasons that this could be happening.  

"Age versus Semen" since it often seems like an adversarial situation.  LOL

Blue Chew has gotten a lot of hype.  Anyone here use it?

Isn't it just a fancy name for sil?

... at a fancy price?

I use it and am very happy with the results. Feel like a high schooler again when I wake up with morning wood

I'd like to try it but isn't it a recurring billing they do?

Yes monthly 20 bucks for 4 pills - I split them in half and they work great!

I guess I could cancel after a month.  I am not gonna be going through packets too fast.  Glad you like the product.  I've heard about it and was intrigued.

and it's cousins Cialis (Tadalafil) and Vardenafil all work in generally the same way by increasing cGMP in the penis by blocking the PDE5 enzyme, people react to the different drugs differently in many cases.  

I use suhagra and tadalafil from india by way of canada with a script. Never had a problem, get the same meds before I had a script from the same company. good old usa shut down access to this company so thats the reason for the script. the india stuff is better than the trial pack my doctor gave me. either you got other issues like diabetes or are looking at injections. how far are you from mexico? I know snowbirds who walked across the border and get a blister pack and are happy with it. although my doctor says it can be inconsistent.
