Ok,
I am a nurse (RN with masters degree). If you take viagra, and do not have issues with impotence, you won't hurt yourself. Viagra does not cause or create any issues with drug dependance. If occasionally you can't get it up, but are fine otherwise, viagra can't hurt you either.
In some cases, if erectile dysfunction is treated at earlier stages more sucessfully if you experience only occasional erectile dysfunction. Late stage erectile dysfunction doesn't respond as well as early stage erectile dysfunction does. In any case, go see your doctor. It's confidential, and there is no shame in it at all. We deal with it VERY frequently in the office, and it's no big deal. A healthy sex life is important to everyone.
But why waste your money? A cure for wiskey dick? don't bother, you'll probably just get light headed and puke on her/his back anyhow.
If you are using Viagra/Cialis/Levitra recreationally remember;
1.) Don't take it if your on ANY heart medication (nitrates)
2.) Don't combine it with excessive alcohol consumption.
3.) Don't take it and go into a hot tub, sauna, or environment with excessive heat. This drug causes a slight decrease in blood pressure, easily tolerated by healthy men, but can become dangerous if you elevate your body temperature at the same time. If you are in this situation and you feel light headed, or nauseated, sit down immediately. If it dosen't subside, drink a glass of water and lay down. If no relief, go to the emergency room.
4.) If your erection is persistently hard longer than 4 hours, go to the hospital. You could have a blood clot. This RARELY happens. But, if so, is better treated sooner than later....your dick could get gangrene, and need to be amputated. remeber 4 hours.
5.) Don't take more than one Viagra every 24 hours (max dose is 100mg/24 hours). Only take one Cialis/Levitra every 36 hours. Do NOT exceed this dose. It could kill you.
6.) Take a Tylenol or Advil with your Viagra. A lot of guys get a bad headache from these kind of medications. If you pre-medicate for the headache, it will not arrive...or will be much less severe.
Enjoy your recreational erection. Play safe and make sure you have someone who wants to play with your penis, or you could sprain your elbow.
