Trying to IV anything...I've tried to hit my non-existant veigns but theres nothing there, they are so small, twisted and f****d from 3 years of sliceing them up...I just ended up hitting skin and tissue...Went through my veign and tore it up...hurt like hell... I do use Needles and Syrenges for SI purposes and to practise on my arms...Usually I would inject the needle fill it up with blood and squrt it out...weard blood obsession...and seeing if I hit a good veign...usually it was nothing, but I did find this one good veign in the crook of my left arm...But, I could see that becomeing a constant injection sight, and I could lose my arms, not good sense I'm a guitar player I guess I could try my feet there are a ton of good veigns on them...eh whatever...
