Injecting - Nausea from injecting?

[bl0whydr0420]

Swim has just tried injecting for his first time today. Everything has been amazing except for the fact that every time he shoots, he feels quite nauseous, and even threw up once.

swim doesnt feel this before or while the needle is in. only about 2 seconds after he starts pushing the plunger does he get the feeling he's going to throw up. is this normal, and if so whats could it be from? does this mean swim is using too much, or nervousness of injecting a drug for the first time? any ideas? o.o

swim's on syringe four now, its gotten better since the first "hit"(whatever swiy would call it), but the nausea is still there nevertheless. Anything swim can do or will this just be something swim will have to get use to when he goes on this magical journey?

and one more thing. swim tied a shirt around his arm to raise the vessel during the second syringe, and once injected and pulled the needle out, everything shot in the arm and a fair amount a blood just squirted in a stream from swims arm. did cutting the blood cause alot of pressure or something? and is cutting the blood to raise the vessel a bad idea or should swim just not tie so tight.

(sorry if second question was answered in previous thread, swim forgot to search for that question, only the first one which came with no results.)
