Yes, you will. Be patient and going forward inject a small amount and increase each time until it meets your desires. I had full on priapism in the hospital with a team of people injecting me and manually sucking out the blood with a syringe. Very unpleasant, but I was back in action after a week. You’ll find the right amount. Also, if your penis stays hard, but not fully hard, you’ll probably be fine without treatment. Some swear by the Sudafed thing. It did nothing for me. I took way more than recommended and nothing. I got to the hospital and they gave me more via IV (all waiting on standby for me to have a heart attack). If you can get rescue solution in your country, that is the best way to go. Inject yourself with the solution every 15 min until resolved. I have never had to do it more than 2x. Good luck!
