things you guys need to realize when using alcohol...it doens't disinfect...it just moves shit around on your skin...so when you clean the site make one swiping pass...dont rub it around.
the only readily available disinfectant that most people have at home is betadine...betadine=good shit! significantly reduces infectious material AND will allow you to stick the site multiple times without having to rewipe like you would with alcohol
*EDIT* and in regaurds go bbd's comment he's right..NEVER reuse a needle...look at the shit you just took out of yourself...and then it came in contact WITH the air and you're gonna wanna reintroduce it to your body? yeah...if you're careless you deserve a rip roaring infection or even worse... i'm giving you guys this knowledge from what i've learned and am still learning in the paramedicine field...i want ya'll to be safe about doing this so i feel the need to share! hell i even do it..but the risks of doing this are pretty invasive when i'ts on your ear...so follow the simple guidelines i've presented and you should have no problems treating that shit. but just like greg valentino's dumb ass...if you just do whatever the hell..you will pay for it.
