Hey Jaybo1,
First, as you might imagine, I am not a medical professional. So there's that disclaimer. The worst thing that can happen is that you'll develop a case of priapism -- the dreaded rock hard erection that won't go down.
Here's a YouTube video showing the hospital emergency room procedure on a guy who came in still hung like a horse after seven hours. Mind you, this video is not for the faint of heart:

Tonight start with something way below the starting dose that the doctor recommended. I mean way below. You've got tonight, Saturday and Sunday before your appointment. We're not supposed to inject on back-to-back days but many of us do on occasion.
If your tiny, tiny dose tonight doesn't work, consider another injection (your call) tomorrow with a slightly (and I mean slightly) increased amount of the juice.
Please keep Sudafed on hand. Search the board for discussion about Sudafed. It can help with prolonged erections.
Another thing you can do -- that's safe -- is to simply practice injecting. That's right, you can "inject" with an empty syringe. Search this board for "aspirating." Some guys like to draw a tiny bit of blood into the syringe to confirm that they are in the right spot. You can practice aspirating this weekend with no danger whatsoever.
Whatever you do, please be safe. Remember that
the best advice is to just wait for your appointment!Good luck and let us know how it goes.
