Jumper here. I plan on jumping from 16 stories. I plan on drinking a bit as well. My advice is no matter how sure you think you are you most likely will not go on your first attempt. It usually takes jumpers multiple visits to their jump spot before they actually jump. If they ever do. Some jumpers change methods after realizing how difficult it is. I wish you luck.
100%. I went to attempt twice after having my life destroyed by someone. The first time i could look over the edge no problem, but when i climbed over the railing i was shitting myself. The second time i was hanging over the abyss like i was in titanic, and felt far more comfortable. If i was distraught enough, i feel i would have gone that day.
I think something often overlooked is hesitation. If you get to your location and look down, give yourself time to process the fear associated with what u want to do, it's going to become more and more difficult. There's a reason when you go bungee jumping they have you look forward not down, then give you a countdown to pressure you to go. Most places only give you 2-3 countdowns before they move onto the next person. Why? They know the longer you hesitate the less likely you will be able to jump.
Personally, i'll bring a couple baseball sized rocks. Drop them over to test the wind, then jump in the appropriate direction (260ft drop, small landing zone). That is if im able to do it of course.
