If I lived alone, I'd make the same choice you did, since I wouldn't want to be potentially incapacitated with flue-like symptoms for a day or so each week. I personally chose Copaxone because of its favourable side-effect profile. Also, systemic allergic reactions are supposed to be very very rare with Copaxone and post-injection reactions although very scary are very rare and supposed to subside within fifteen minutes or so. So far, no passing out or any other scary stuff for me, just some bruises, lumps and bumps and I'd say more muscle aches and joint pains than before I started on it, but who knows whether it's the drug or MS.
I was completely freaked out at the beginning-- I can't tell you how much I hated all the promotional stuff they sent me-- it was a constant, unwanted reminder of this freakish illness I never ever in my wildest dreams thought I'd have to deal with. I thought that even if some kind of a weird side-effect doesn't get me, an anxiety attack will!
Everyone is different, but I personally turned a corner when I ditched their autoinject-- not having to set up a field hospital in my bathroom with all the paraphernalia they give you was for me a huge improvement, also my site reactions got much better with manual injecting. It's a thin needle and only goes under your skin-- I also took B-12 injections for while (those go in your muscle) and found them sooo much more traumatic than injecting sub-Q! I'm at the point where injecting is really and truly not a big deal at all-- a pain in the buttocks (no pun intended!) chore but not something I ever dread. Time also helped-- for lots of people, the longer you do it the more your body gets used to it, so it reacts less. So don't chicken out-- I'm sure you've been through a lot worse and this is not very likely to hurt you and it just might help! Best of luck to you!
