I didn't mean that 1/3 of my shots are successful in that the other 2/3 I miss. I make sure I am in the vein and if I slip out I pull back the plunger and see if more blood comes up. I am actually pretty good at shooting I just have hard to see veins, and when I abuse them they are even hard to hit. I give them a break and they become more visible and easier to hit. I am gonna start working out so they become more visible. I have shot up three friends, all with easier veins to see then mine and got it the first time every time. Also, unfortunately the easiest vein I have to hit is in the right crook out my elbow and my left hand is a little shaky. The other night I was halfway done with a shot and my kitten came in the door and scared me and I missed the rest of the shot, lol. Plus you guys know once you go IV you don't go back. The only time when I miss is occasional fuck ups like I mentioned above, or if I get lazy and think I am the vein after a while of trying to hit it and inject but I am going to stop doing that, it's a waste of dope and harmful to my health. I have to gain patience, this girl I hang with has worse veins than me and the other night she sat their for two hours trying to hit it with a blood filled syringe, but she made sure she was in.
