I can feel for your plight. I was finding the same problem using injections for the same purpose *remember me Mustang? and also taking up to 400mg (not a typo) of Viagra to get an effect.
My doctor then warned me of serious heat attack risks by taking so much. So I tapered down to 200mg. Now I take 50mg successfully. What is the reason?
Viagra only HELPS you get an
Erection. It won\'t give you one. If 50 or 100mg doesn\'t work, look elsewhere for the problem. Who is it you\'re trying to get aroused to? Maybe she\'s the wrong person. Yeah, it doesn\'t mean you don\'t love her, it merely means she doesn\'t turn you on that way.
Now I can even perform fine without any Viagra because my GF is Viagra in human form, smoking hot and wild as a tigress. I do take it to endure, just 50mg just in case and especially to be ready for round 2 quickly.
So all I can advise is to keep your dosage reasonable and to figure out why it isn\'t working rather than taking more.
Cheers,
