How long have you been fixing? Are you just starting out and having problems finding a vain or have you hammered the sites you have been using a wile?
*Edit sorry Ive re-read and sounds like your new to the game. The first thing I would suggest is don't fix it unless its not working for you any other way, Ive been shooting for years and trust me its over rated, yes the fist few are great but it all end up the same in the end and wearing long sleeves in the summer sucks balls.
If you can see a vain in your arm you can shoot in it. Its all down to technique, feeling the vain pop and pulling back to confirm. Use a torny and loosen it before pushing the gear in. The best way would be to show you, if you have skype or suchlike I will give you a demo ( and also show you what 10 years of IV drug use does to you veins ( and self respect, I have had mornings crying, whilst covered in blood unable to get a hit)).
Again I bring you to my first point, find another method! Smoke a joint, have a cheeky wank, just don't get into shooting the gear.
