what you need to do, allosudden,

Is GO SEE A UROLOGIST AND AN INTERNAL MEDICINE SPECIALIST. That's it - the only sane advice possible. No one on this board can or should provide any advice beyond this obvious action.

LG,
What is a guy to do when viagra doesn't work anymore?
I've had ED since the age of 30 and been able to have a great sex life due to viagra, cialis, levitra but in the last 18 months it has not worked at all.
I have no undo stress in my life, things are good at work. It just stopped working.
I'm a bit lost as to what to do. Any advice?

I hope this dosen't get me moderated, but I have one question.  Are you using meds from a legitimate pharmacy or from some online site made who knows where and containing who knows what?  If so it may be the meds and not you.

Have you asked him or her? That's a good place to start. Ask the doctor who prescribed that medication to you.
