I agree it's a dart board type of choice sometimes, LOL!

I chose Copax as my first since the side effects listed were less than the others. Unfortunately, I was one of the few that got Immediate Post Injection Reactions (IPIRs) which became too much for me.

Rebif was always my second choice since it's only three times a week. Which after being on a daily shot takes some getting used to.

Best of luck with whatever you choose.
